Memory Management For Embedded And Iot Kernels: Master Resource-Constrained Systems Using SLAB, SLUB, Memory Pooling, and Predictable Performance Techniques

By M.T Holbrook

Memory is the most precious resource in embedded and IoT systems. A poorly managed allocator can mean the difference between a product that ships on time and one that fails in the field-draining batteries, missing real-time deadlines, or crashing under load.
This practical guide cuts through the complexity of kernel memory management and gives you the tools to build systems that are both efficient and predictable. Whether you're working with wearables that have mere megabytes to spare or edge gateways managing thousands of concurrent connections, you'll learn exactly how to make every byte count.
What You'll Master: Understand the fundamentals of memory architecture in resource-constrained kernels, from page-based systems to custom allocation strategiesChoose between SLAB and SLUB allocators with confidence, armed with benchmarks, trade-offs, and decision frameworks tailored to your hardwareDesign and implement memory pools that eliminate allocation latency and reduce fragmentation in performance-critical code pathsAchieve deterministic behavior through careful memory management, ensuring your systems meet real-time deadlines even under pressureDebug and profile effectively using practical techniques to find leaks, track fragmentation, and optimize allocator behaviorLearn from real products through case studies spanning wearables, industrial sensors, and edge computing platformsEach chapter blends theory with actionable techniques. You'll find configuration examples, tuning parameters, debugging strategies, and code patterns you can adapt immediately. The appendices provide quick-reference guides and starter templates for your own implementations.
Why This Book Matters:
Memory management in embedded systems isn't glamorous, but it's foundational. Get it right, and your devices run smoothly for years. Get it wrong, and you're chasing mysterious crashes and performance issues in production. This book ensures you get it right.
Perfect for embedded systems engineers, kernel developers, and technical leads who refuse to leave performance and reliability to chance.
