RTOS Benchmark: A Test Suite for Measuring Core Operation Performance of Real-Time Operating Systems

RTOS Benchmark is a test suite specifically designed to measure the core operation performance of Real-Time Operating Systems (RTOS). It quantifies the time and overhead of basic operations such as thread creation/switching, mutex/semaphore, timers, and message queues through a series of benchmark tests. Currently, it mainly supports Zephyr (qemu_x86, frdm_k64f) and FreeRTOS (frdm_k64f), with plans … Read more

Essential for Embedded Systems! Slimming Down the C Standard Library to Just a Few KB: Practical Notes on picolibc

In simple terms, picolibc is a C standard library (libc) tailored for small embedded devices. It combines the essence of newlib and AVR Libc, targeting systems with extremely limited memory—capable of running on a variety of architectures such as MSP430, RISC-V, ARM, ESP32, and MIPS. The focus is on being small, fast, and testable. Why … Read more
