Laquo; Are We Shooting Ourselves in the Foot with Stack Overflow? Beyond the RTOS: A Better Way to Design Real-Time Embedded Software. Fast, Deterministic, and Portable Counting Leading Zeros. Monday, September 8th, 2014 by Miro Samek. Counting leading zeros in an integer number is a critical operation in many DSP algorithms, such as normalization of samples in sound or video processing, as well as in real-time schedulers to quickly find the highest-priority task ready-to-run. For example, ARM Cortex-M0 ...
