摘要
提出了一种基于ARM9+DSP双核处理器OMAPL-138和FPGA的合并单元设计方案。给出了该方案的原理框图,以及具体的程序流程图,并在CCS开发环境下完成了软件编程,实现了合并单元按照IEC61850标准规定的格式进行数字量以太网传输。实验结果证明了该设计方案的可行性与正确性,为合并单元的设计提供了一种新的思路。
A design of combined unit based on ARM9＋DSP dual core processor OMPL-138 and FPGA is proposed. Functional block dia- gram and the specific program flow of the design are given, software programming is accomplished in the CCS developing environment, and digital quantities of the combined unit are realized to transmit through Ethernet according to IEC61850 standard format. Experimen- tal results show the feasibility and correctness of the design and the design provides a new idea of combined unit.
