At the core of the majority of financial innovations lies C++, a language revered for its speed, efficiency, and control.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">As financial institutions continue to incorporate advanced electronics and embedded systems into their operations\u2014be it through the ATMs we rely on for banking transactions, the sophisticated high-frequency trading platforms, or the secure transaction systems that protect our finances, C++ has become an indispensable tool.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Embedded systems are central to the proliferation of financial services which require real-time processing capabilities that only a highly performant language like C++ can provide. The financial sector\u2019s demands for speed, precision, and security make C++ the language of choice for developers tasked with building the systems that underpin our financial infrastructure.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In this blog, we explore how C++ is used in these mission-critical financial systems. We\u2019ll examine why it is suitable for embedded systems in finance.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Embedded systems in financial services<\/span><\/h2>\n<h3><span style=\"font-weight: 400;\">What are embedded systems?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Embedded systems are specialized computing systems designed to perform dedicated tasks within larger devices or systems. Unlike general-purpose computers, they are optimized for specific functions, often operating with real-time constraints and limited resources. Common examples of embedded systems include automotive control units, medical devices like pacemakers, and home appliances such as microwaves or washing machines. These systems are crucial in industries requiring precise control and efficiency, even outside the financial sector.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">How embedded apps and digitalization are transforming financial software<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">The primary driver of the increasing demand for embedded systems is digitalization. Or to be more specific, inevitable progress in tech is opening more ways to serve underbanked communities; these opportunities require more and more digital alternatives to traditional banking.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">About two decades ago, the fintech model relied on singular banks serving a whole community. Today, every business is expected to accept payments through digital platforms, credit cards, and other payment platforms. This has <\/span><a href=\"https:\/\/builtin.com\/articles\/embedded-finance\"><span style=\"font-weight: 400;\">minimized the red tape<\/span><\/a> and payments and financial services\u00a0<span style=\"font-weight: 400;\">have become more seamless.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For instance, e-wallets and banking apps on smartphones have certainly made financial services easier to access, however, physical devices must still be available for businesses to use as terminals and portals for digital transactions. <\/span><b>This is where embedded systems on devices come in.<\/b><\/p>\n<h3><span style=\"font-weight: 400;\">Examples of Embedded Systems used in financial services<\/span><\/h3>\n<h4><b>Point-of-Sale (POS) Systems<\/b><\/h4>\n<p><span style=\"font-weight: 400;\">POS systems are ubiquitous in retail stores, restaurants, and other businesses that accept payments. These systems integrate embedded processors and software to handle various functions like:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Accepting credit\/debit card payments<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Tracking inventory and sales data<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Generating receipts and reports<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">POS terminals are essentially embedded computers designed for payment processing and business management.<\/span><\/p>\n<h4><b>ATMs (Automated Teller Machines)<\/b><\/h4>\n<p>ATMs are self-service banking kiosks that contain embedded systems in the form of peripheral devices. Embedded systems help the main PC operating system manage the user interface, cash dispenser, and card reader. It can also communicate with the bank&#8217;s central computer system.<\/p>\n<h4><b>Contactless Payment Terminals<\/b><\/h4>\n<p><span style=\"font-weight: 400;\">Contactless payment terminals are embedded systems that enable customers to make payments by tapping or waving their credit\/debit cards or mobile devices near the terminal. These terminals use near-field communication (NFC) technology and are commonly found at retail checkouts and transit fare gates. Smartwatches, fitness trackers, and other wearable devices can be embedded with payment capabilities.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Section 2: C++ in finance and banking<\/span><\/h2>\n<h3><span style=\"font-weight: 400;\">Why financial embedded systems use C++<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Embedded systems use C++ because it lets developers control hardware directly while still keeping the code organized and easier to manage.There is a good mix of low-level hardware control and high-level programming abstractions.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">C++ is great for devices with limited memory or processing power, like small sensors or controllers, because it helps the code run fast. It also allows developers to write code that can work on different types of devices without starting from scratch. This makes C++ a popular choice for many embedded systems. Additionally, C++ offers portability, making it easier to adapt code across different embedded platforms.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">The demands of financial software<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">In the financial sector, software systems face exceptionally high demands. These systems must deliver extreme performance, steadfast reliability, and robust security to support critical functions like real-time trading, transaction processing, and risk management. The stakes are incredibly high, as even minor software failures can result in significant financial losses, security breaches, and a loss of client trust.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">C++ is well-equipped to meet these rigorous requirements. Renowned for its speed and efficiency, C++ enables developers to create high-performance applications crucial for environments where every millisecond can impact trading results. Its <\/span><a href=\"https:\/\/www.schlogl.com\/docs\/qf\/\"><span style=\"font-weight: 400;\">low-level memory<\/span><\/a><span style=\"font-weight: 400;\"> control allows for precise management of system resources, ensuring both stability and responsiveness in financial systems. Additionally, C++ is supported by a comprehensive suite of libraries designed for complex financial operations, making it an ideal choice for developing secure and high-performing financial software.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Advantages of the C++ language in Financial Software<\/span><\/h3>\n<table>\n<tbody>\n<tr>\n<td><b>C++ Property<\/b><\/td>\n<td><b>How it compares to other languages used in finance<\/b><\/td>\n<\/tr>\n<tr>\n<td><b>Lower level language<\/b><span style=\"font-weight: 400;\">: C++ code compiles into highly efficient machine-like code, providing real-time processing capabilities and scalability.\u00a0<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Faster than interpreted languages like Python or JavaScript, which are unsuitable for real-time performance requirements.<\/span><\/td>\n<\/tr>\n<tr>\n<td><b>Speed and performance<\/b><span style=\"font-weight: 400;\">:Handles intensive computational tasks with minimal overhead, making it ideal for high-performance applications.\u00a0<\/span><\/td>\n<td><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\">Similarly popular in finance programming, Python offers simplicity and faster development cycles.

Financial applications, such as high-frequency trading platforms and real-time risk management systems, operate under intense performance constraints where even the <\/span><a href=\"https:\/\/blog.epmainc.com\/how-optimization-drives-financial-growth-unleashing-profitability-through-strategic-efficiency\/\"><span style=\"font-weight: 400;\">smallest delay can have significant repercussions<\/span><\/a><span style=\"font-weight: 400;\">. As a result, C++ developers are tasked with continuously fine-tuning their code to meet performance requirements.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">One of the primary challenges in this optimization process is <\/span><b>managing memory<\/b><span style=\"font-weight: 400;\">. C++ provides low-level control over memory allocation, which allows for precise performance tuning but also demands that developers manually handle memory management. This responsibility includes careful allocation and deallocation to prevent memory leaks and ensure efficient resource utilization.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Additionally, <\/span><a href=\"https:\/\/blog.epmainc.com\/how-optimization-drives-financial-growth-unleashing-profitability-through-strategic-efficiency\/\"><b>reducing latency<\/b><\/a><span style=\"font-weight: 400;\"> is crucial in financial applications where timely processing of data and execution of trades are essential. Developers must implement strategies to minimize latency, which involves optimizing algorithms, data structures, and reducing the impact of I\/O operations. Productivity enhancing tools such as <\/span><a href=\"https:\/\/www.wholetomato.com\/en\/features\/feature-refactoring\"><span style=\"font-weight: 400;\">Visual Assist C++<\/span><\/a><span style=\"font-weight: 400;\"> that simplify refactoring help here immensely as they can help spot unnecessary elements\u2014more on helpful tools later.\u00a0<\/span><\/p>\n<p><b>Maintaining code quality<\/b><span style=\"font-weight: 400;\"> while optimizing performance presents another challenge. Performance enhancements often <\/span><a href=\"https:\/\/learn.microsoft.com\/en-us\/training\/modules\/apply-basic-performance-optimization-finance-operations\/\"><span style=\"font-weight: 400;\">require low-level changes<\/span><\/a><span style=\"font-weight: 400;\"> to the code, which can complicate readability and maintainability. Balancing the need for high performance with the necessity of keeping the codebase understandable and manageable is a continuous struggle for C++ developers working in the finance sector.\u00a0<\/span><\/p>\n<p><b>Readability <\/b><span style=\"font-weight: 400;\">is an often underestimated facet of development. Embedded code can often be hard to read, or drop from C++ to lower-level C. For instance, when accessing IO pins on an embedded device via a cable plugged into &#8220;general purpose IO pins&#8221; (GPIO) you have to use the base-level language that can communicate with the hardware itself.\u00a0 At that point, it&#8217;s key to have <\/span><a href=\"https:\/\/www.wholetomato.com\/en\/features\/feature-code-understanding\"><span style=\"font-weight: 400;\">tooling that helps you understand and verify your code<\/span><\/a><span style=\"font-weight: 400;\"> when you run it back from higher and lower abstraction between languages.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">As simple as possible: C++ vs Embedded C++<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">When discussing C++ versus Embedded C++, it\u2019s essential to understand that while they share a common language foundation, the environments in which they are applied significantly influence the design, usage, and constraints of these two variants.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The main difference with C++ in embedded systems is that it has to be more efficient because devices often have limited memory and processing power. Embedded C++ also involves directly controlling hardware, like sensors and processors, which isn\u2019t as common in traditional C++. Finally, some C++ features, like dynamic memory management, are used less or even avoided entirely in embedded systems to avoid performance issues. Rather than using the standard STL, it\u2019s common to use other libraries tailored for embedded use, like the <\/span><a href=\"https:\/\/embeddedartistry.com\/blog\/2018\/12\/13\/embedded-template-library\/\"><span style=\"font-weight: 400;\">ETL<\/span><\/a><span style=\"font-weight: 400;\">.<\/span><\/p>\n<ul>\n<li aria-level=\"1\">\n<h4><b>Memory management and constraints<\/b><\/h4>\n<\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">C++ on a desktop or server system operates in a much more forgiving environment. It has access to extensive memory, high processing power, and can rely on an operating system for memory management and multitasking. In contrast, <\/span><b>Embedded C++<\/b><span style=\"font-weight: 400;\"> targets microcontrollers or other resource-constrained devices, where memory (both RAM and flash) is limited, and there may not be an operating system at all.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For instance, in an embedded system, dynamic memory allocation using new and delete can be risky due to fragmentation, leading to memory exhaustion over time. Many embedded systems developers avoid heap allocation entirely, preferring static or stack allocation, or using custom <\/span><a href=\"https:\/\/github.com\/ETLCPP\/etl\"><span style=\"font-weight: 400;\">memory management techniques<\/span><\/a><span style=\"font-weight: 400;\"> tailored to the system&#8217;s constraints.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Some devices\u00a0 such as ATMs or POS systems need a small amount of <\/span><a href=\"https:\/\/www.techtarget.com\/searchstorage\/definition\/flash-memory#:~:text=Flash%20memory%2C%20also%20known%20as,enterprise%20systems%20and%20industrial%20applications.\"><span style=\"font-weight: 400;\">flash memory<\/span><\/a><span style=\"font-weight: 400;\">, a form of non-volatile memory, to keep a small database. For example, some systems need to keep the past 24 hours of transactions on the system itself as a backup for when the bank network has gone down unexpectedly. For these cases, reliable memory-efficient libraries for <\/span><a href=\"https:\/\/github.com\/atomicobject\/heatshrink\"><span style=\"font-weight: 400;\">compression<\/span><\/a><span style=\"font-weight: 400;\"> and <\/span><a href=\"https:\/\/rocksdb.org\/\"><span style=\"font-weight: 400;\">embedded databases<\/span><\/a><span style=\"font-weight: 400;\"> are used.<\/span><\/p>\n<ul>\n<li aria-level=\"1\">\n<h4><b>Performance and real-time requirements<\/b><\/h4>\n<\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Another significant difference arises in performance and real-time behavior. In standard C++ applications, performance is still important, but not necessarily tied to hard real-time requirements.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In contrast, embedded systems often have strict timing constraints, and code must execute within a specific time frame to meet system requirements. This demands careful optimization and the avoidance of certain C++ abstractions that can introduce unpredictable execution times.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For example, C++ standard library features like the Standard Template Library (STL) may not be suitable for embedded environments. Functions like std::vector or std::map can introduce hidden memory allocations and performance overhead, which can be detrimental in a real-time system.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">As a result, embedded C++ developers often resort to using lightweight custom libraries or writing their own data structures optimized for their specific hardware. You can use libraries like the <\/span><a href=\"https:\/\/github.com\/ETLCPP\/etl\"><span style=\"font-weight: 400;\">embedded template library<\/span><\/a> <span style=\"font-weight: 400;\">that provides STL-like functionality intended for embedded devices.

This entails hardware-specific code, where developers directly manipulate memory-mapped registers to control the device.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In standard C++, you rarely deal with such low-level hardware specifics. Embedded C++ developers, however, often need to interact directly with hardware registers and bit manipulation, as shown in the examples with the ATM or POS systems. This introduces a level of complexity not typically found in standard desktop or server C++ development.<\/span><\/p>\n<ul>\n<li aria-level=\"1\">\n<h4><b>Debugging Challenges<\/b><\/h4>\n<\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Due to the very <\/span><i><span style=\"font-weight: 400;\">embedded <\/span><\/i><span style=\"font-weight: 400;\">nature of embedded systems, debugging is inherently more complex due to the lack of typical debugging resources available in standard C++ environments. Desktop developers can rely on sophisticated debuggers, full IDEs, and graphical interfaces to step through code, inspect memory, and trace program execution. In contrast, embedded developers often work without these luxuries.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Debugging tools may be limited to physical devices that <\/span><i><span style=\"font-weight: 400;\">plug into<\/span><\/i><span style=\"font-weight: 400;\"> the circuitry, or maybe testers and emulators that merely simulate the device.
