Understand why CPU clock speed alone cannot predict MCU performance. Learn how IPC, pipelines, memory wait states, caches, buses, compilers, and workload shape real embedded throughput.
A practical guide to the CoreMark benchmark: what it measures, how CoreMark/MHz is calculated, how it compares with DMIPS, and how to use benchmark results without mistaking them for application performance.
Clear explanation of hardware FPU, VPU, NEON, and SIMD instructions and their massive impact on CPU performance. Real benchmarks, use cases, and comparisons showing 10-100x speedups in signal processing, graphics, ML, and math-heavy applications.
A beginner-friendly, comprehensive guide to understanding CPU, GPU, and NPU: what they do, how they differ, their architecture, real-world use cases, pros and cons, and when to use each for your project. Perfect for engineers and developers.
A practical guide to choosing between ARM Cortex-M microcontrollers and Cortex-A processors for embedded projects. Learn the architectural differences, performance trade-offs, real-world use cases, and decision criteria for MCU vs MPU selection.
Deep-dive into DMIPS vs MIPS: what Dhrystone measures, why MIPS alone is misleading, how to interpret DMIPS specifications in MCU datasheets, and what these metrics actually tell you about real-world performance.
A practical engineer-friendly guide to CPU and MCU performance metrics in embedded systems. Learn what MHz, MIPS, DMIPS, CoreMark, CoreMark/MHz, and FLOPS really mean, when they help, when they mislead, and how to select the right processor for real workloads.
