ARM’s strategies to address the challenges of IoT devices are primarily reflected in the following aspects: 1. Low Power Design: ARM processors are highly efficient, making them particularly suitable for battery-powered IoT devices. By optimizing architecture and manufacturing processes, ARM can significantly reduce power consumption while maintaining performance, thereby extending the device’s lifespan. 2. Security: … Read more
Recently, I encountered a problem where threadx running on ARM crashed when communicating with DSP using message queues (the underlying implementation is through interrupts and shared memory). During the troubleshooting process, it was found that the structure used for message passing did not consider the issue of byte alignment. Here, I will整理一下 the issue of … Read more
