摘要
在双CPU系统中处理好两个CPU间的通信,是系统设计的关键。本文设计采用双口RAM实现ARM与DSP间通信,并利用中断逻辑解决端口争用问题,从实际运行情况看,完全满足双CPU系统中两个处理器间高效、实时、稳定的通信。
In the double CPU system handle the communication between two CPU,is the key to the system design.This design USES the dual port RAM to realize the communication between ARM and DSP,and use the logic of interrupt port to solve the port contention issues,according to the actual operation,ful y meet the double CPU system between two processors in efifcient,real-time and stability of the communication.
