FPGA作为协处理器的中断扩展管理

Interrup Extending Management Using FPGA as Coprocessor

阐述了系统中断扩展的方法,并分析了其优缺点。基于常用的微处理器+FPGA系统构架,提出了一种基于FPGA的外部中断管理扩展方法,可以充分利用FPGA的优点,从而克服传统方法的不足。

The traditional method of interrupt expanding management is introduced, and its benefits and disadvantages are analyzed in this paper. Based on the most popular architecture of MPU＋FPGA. A new FPGA-based method for extending the external interrupt management is proposed to overcome the disavantage of the traditional method using the advantase of FPGA.
