In ARM-based MCU subsystems, there are only 240 peripheral interrupts available. Therefore, for a large number of interrupts, a secondary lookup is necessary. The cost of this approach is that it cannot achieve timely system responses, as it requires time to read the status registers.This article introduces the method of compressing interrupt signals and the … Read more

FPGA: The Communication ‘Transformers’ Born for Extreme Environments The ‘Rigidity’ Pain of Emergency Communication In the event of natural disasters or emergencies, communication infrastructure often bears the brunt. Base stations collapse, fiber optic cables are cut. Conventional communication methods fail instantly. At this moment, the communication capability of rescue teams directly affects the efficiency of … Read more
In embedded development, precise delay control is crucial for many applications, especially in scenarios such as sensor sampling and protocol timing control. Traditional methods of implementing delays often rely on simple for loops; however, this approach not only lacks precision but also wastes a significant amount of CPU resources during long delays. To improve delay … Read more
