Workload-Aware Performance Profiling of IoT Microcontrollers: A Cross-Architecture Benchmark Across Compression, Cryptography and Signal Processing
This study compares active-computation energy and latency for twelve compression, security/integrity and signal-processing workloads on ESP32, RP2040 and STM32F446. Common scalar C kernels process fixed 2048-byte inputs on one application core under two operating profiles: maximum nominal CPU clocks of 240, 200 and 180...
