Modern C++ for Embedded Systems: Zero-Overhead Abstractions, Static Memory, and Real-Time Patterns for Bare-Metal and RTOS Targets. (High-Performance C++ Engineering)

In embedded systems, memory is finite and execution deadlines are absolute. Stop letting overhead myths dictate your firmware architecture.For decades, embedded engineers have treated C++ with suspicion, fearing bloated binaries, hidden heap allocations, and unpredictable runtime latency. As a result, countless mission-critical systems are still built using unsafe C patterns, relying on void pointers, brittle macros, and manual resource management. But the landscape of compiler technology has changed.Modern C++ for Embedded Systems shatters the misconception that C++ is unsuitable for constrained environments. This definitive guide demonstrates how to harness the power of modern C++ (C++20/23) to build highly complex, type-safe, and incredibly fast firmware for bare-metal microcontrollers and RTOS targets—without sacrificing a single byte of flash or a single cycle of CPU time.Whether you are targeting an ARM Cortex-M, deploying on Zephyr, or writing bare-metal drivers from scratch, this book provides the exact blueprints for writing zero-overhead C++ that compiles down to the tightest possible assembly.What You Will Learn Inside:The Reality of the Embedded Runtime: Master compiler flags, disable exceptions and RTTI, and verify your true footprint by analyzing map files and disassembly.The Forbidden Heap: Completely eliminate dynamic allocation from your hot paths. Implement stack-resident fixed-capacity containers, object pools, and lock-free ring buffers.Zero-Overhead Abstractions: Use template metaprogramming, constexpr, and tag dispatch to build policy-based hardware drivers that emit absolutely no branch instructions at runtime.Type-Safe Hardware Access: Map registers to strong typedefs, ensuring that invalid pin configurations, address faults, and incorrect state machine transitions fail to compile at all.Deterministic Interrupts: Design lock-free, atomic communication pathways between Interrupt Service Routines (ISRs) and the main context without compromising ARM memory ordering.RTOS Integration: Safely wrap FreeRTOS primitives (tasks, mutexes, queues) in zero-leak RAII C++ objects. Understand stack sizing and Worst-Case Execution Time (WCET) for C++ tasks.Zero-Copy Peripheral Drivers: Build asynchronous, DMA-backed SPI, I2C, and UART drivers using std::span and std::bit_cast to process wire bytes in place.Field Protocols and OTA: Implement robust CAN Bus, Modbus, and lwIP networking logic, alongside highly secure Over-The-Air (OTA) update state machines.Stop trading architectural safety for performance. You can have both.Get your copy today and learn how to engineer embedded systems that are radically safer, exponentially more maintainable, and just as fast as raw C. Read more
