Assembly and C for Embedded Systems: Integrate Assembly and C to Control Hardware, Handle Interrupts, and Optimize Performance

Master RISC-V Assembly and C to Build Real-World Embedded Systems—From Bare Metal to Linux in 2025 and Beyond Whether you're an embedded systems developer, computer engineering student, or curious hardware hacker, this hands-on guide teaches you how to program real RISC-V systems using modern assembly and C. With concise, working examples and up-to-date workflows, this book helps you go from flashing an LED on bare metal to running a minimal Linux user space on RISC-V hardware or emulators. Written for the generation of embedded engineers, this book blends RISC-V ISA fundamentals, assembly-C integration, toolchain usage (GCC, QEMU, OpenOCD), and practical I/O projects like UART shells, PWM motor control, and RTOS integration. You’ll learn how to build, debug, and optimize embedded applications using cycle-accurate profiling, GDB debugging, and energy-aware code design. You'll also explore emerging trends such as Edge AI on RISC-V, Linux boot sequences, device trees, and secure extensions—making this book essential for both current practitioners and future-proof learners. Why this book? Complete, working code explained step by step Based on real RISC-V boards, emulators, and Linux setups Up-to-date with RISC-V tools and trends as of 2025 Teaches debugging, profiling, and performance tuning Builds projects grounded in industry practices
