摘要
分析了构建基于异构多核微处理器嵌入式数控系统的几大关键技术,包括:软硬件结构、高速现场总线技术、多核处理器核间通信机制。给出了原型系统的设计与实现细节,重点阐述了基于多核通信中间件DSPLink的SSB-Ⅲ现场总线驱动程序的具体实现,最后针对影响系统性能的中断延迟时间进行了评测,为高性能嵌入式数控系统的进一步开发奠定了基础。
Several key technologies for building Heterogeneous multicore microprocessor based embedded NC system were analyzed in this paper, which include Hardware and Software architecture, Highspeed field bus technology, Communication mechanism between cores of multicore processor. A proto type system was given together with its design ＆ implementation. Especially, this paper illustrated the detailed implementation of field bus diver based on DSPLink, which is a middleware for communication between multicores. Finally, this paper completed the measurement of interrupt latency which affects system performance. This paper makes some contribution to the further development of highperformance embedded NC system.
