Host Port Interface of DSP implements interprocessor communication.
处理器之间的通信由dsp的主机接口实现。
Meanwhile, with the growing of the system size, interprocessor communication overhead more and more become a bottleneck.
同时,随着系统规模的不断扩大,处理器之间的通信问题变得越来越突出。
The paper discusses the resource management, interprocessor communication, process control, state monitor and error processing, which are important technical problems for RCDOS.
