Exploring the Significance of JPEG Decoding on Resource-Constrained Systems in the Cortex-M Platform

IntroductionFor embedded product development, cost is the most fundamental consideration. Even if the conclusions are similar for the same problem, they often have completely different paths in different contexts. Take the question of whether “JPEG software decoding on the Cortex-M platform is meaningful” as an example; the thought process here is quite typical:First, the Cortex-M … Read more

Guide to Building an RTOS Kernel (Part 1)

1IntroductionImagine if the MCU we work with only runs bare-metal programs; when it reaches a thread that includes a delay, our CPU would start to “idle”.To maximize CPU utilization, we need to use an RTOS (Real-Time Operating System). In simple terms, an RTOS is an operating system that schedules all available resources to complete real-time … Read more
