基于多处理器系统的超级指令任务调用实现

Implementation of Task Call Based on Multiprocessor SoC

介绍了一种新型的超级指令任务调用方法,该任务调用方法基于单芯片多处理器架构,它由一个主处理器和三个从处理器构成;在该系统中,终端用户无需掌握应用领域中复杂的、底层的专业算法,这些算法可以由底层的算法工程师事先集成在各个从处理器中,而终端用户只需要对主处理器进行编程;当主处理器的应用程序需要调用某个算法程序的时候,只需要发送一条超级指令给相应的从处理器,该算法程序就可以由从处理器独立完成,这种任务调用方法大大简化了多处理器任务调用,提高了整个系统的并行工作能力。

This paper presents a new methodology of task call named super instruction task call. The method is based on a multiprocessor SoC （MPSoC） which is composed of one master and several slaves. In this kind of system, the user doesn＇ t need to know the details of the complicated algorithms in the application field, Those algorithms could be programmed in the slaves in advance. The user only programs the master. When it needs a task call, the master sends the super instruction to some slave, and that slave will complete the task independ ently. This method greatly simplifies task call and improves the parallelism of the whole system.
