Click the blue WeChat name below the title to quickly follow With the continuous development of process nodes (now commonly at 28nm, 22nm, 16nm, 14nm, and even some at 7nm), the performance demands of chips are increasing, and their scale is growing larger. Digital IC design engineers are becoming increasingly concerned about chip power consumption, … Read more
After years of low-power hardware design (the hardware and software design in the company are separate, and I have always been doing hardware. Facing low-power production issues in hardware can often be quite challenging), I found that one common issue is that the IO is not configured properly before the microcontroller enters sleep mode. The … Read more
This issue’s topic: Low Power Design Ideas Based on RTOS.
