Efficient C Programming: Build Embedded and OS-Level Systems with Confidence

Efficient C Programming
Build Embedded and OS-Level Systems with Confidence
Unlock the full potential of C to build high-performance, low-level applications that interact directly with hardware, operating systems, and embedded environments. Efficient C Programming is the definitive guide for engineers, developers, and system architects who want to push beyond basic syntax and master the core principles of writing fast, efficient, and memory-safe C code for real-world use.
This book dives deep into the essentials of systems programming with C, delivering hands-on techniques to write powerful embedded firmware, create OS-level tools, and craft resource-optimized applications where performance and reliability are critical.
What you’ll learn:

• Write high-efficiency C code with a deep understanding of memory layout, pointers, and CPU-level optimization
• Design and build bare-metal applications and real-time embedded systems using microcontrollers
• Develop OS-level tools, utilities, and system calls with direct access to low-level APIs
• Master memory management techniques, including manual allocation, stack vs heap dynamics, and buffer safety
• Apply hardware-aware programming principles for predictable timing, low power consumption, and hardware interfacing
• Optimize critical routines for performance and portability using inline assembly and bit-level operations
• Explore C99/C11 features, modular design, and secure coding patterns in system-critical contexts
• Use cross-compilation, debugging tools, and profiling to tune your code for target platforms

Key Features:

• Project-Based Learning: Build firmware, command-line tools, and OS utilities with full code examples
• Hardware-Centric Approach: Learn how to interact with registers, memory-mapped I/O, and timers
• Deployment-Ready Concepts: Covers build systems, linker scripts, and production-grade optimization
• Security and Stability Focus: Defensive programming, buffer overflows, and safe C practices
• Industry Relevance: Learn techniques used in operating systems, IoT devices, robotics, and aerospace software

If you’re ready to move beyond the basics and harness C for building dependable, low-level software that operates at the heart of machines, this book will be your hands-on companion from concept to deployment.
