Application of LS2K1000LA Processer in Domestic Excitation Control Systems
The fully domestication of excitation systems for power plants is an inevitable trend.The Loongson LS2K1000LA processor,which adopts the fully domestic LOONGARCH instruction set,is used as the core for the non-real-time tasks in the fully domestic excitation control system.Two communication interfaces,USART and SPI,are used to realize the high-speed and low-speed data exchange between LS2K1000LA and GD32F450ZI.The strict timing prob-lem in the SPI bus communication between LS2K1000LA and GD32F450ZI is solved with interrupts and DMA.Then,problems that occurred during the application of the LS2K1000LA processer are analyzed.The application processes of the board bootloader PMON,kernel,and file system of LA464 CPU are introduced.It provides valuable ideas for the de-vice domestication.
