RTOS Kernel Optimization: Achieve 0.1μs Response Time
PART.01Performance Kill: Three Major Tricks to Push RTOS Kernel to the Limit1. Interrupt Response: The “Bloody Evolution” from μs to Clock Cycles Traditional Solution: FreeRTOS default interrupt latency ≥5μs (some industrial control devices measured directly up to 8.7μs); Huawei Black Technology: L1 Cache Preloading Mechanism (measured on Hisilicon Hi1812 chip): T_{latency} = T_{int} + \lceil … Read more
