摘　　要：发电厂励磁系统全国产化是必然趋势。采用全自主LOONGARCH指令集的龙芯LS2K1000LA处理器作为全国产化励磁控制系统中非实时任务的核心,采用USART和SPI两种通讯接口实现LS2K1000LA与GD32F450ZI之间的高速和低速数据交互,通过中断和DMA方式解决LS2K1000LA与GD32F450ZI之间SPI总线通讯时苛刻时序问题,分析了LS2K1000LA使用过程中出现的问题,介绍了使用LA464 CPU的板卡引导程序PMON、内核和文件系统的步骤。为器件全国产化提供了有借鉴价值的思路。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 problem 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 device domestication.
