基于消息机制的片上多处理器系统的研究

Research of On-chip Multiprocessor System Based on Message Mechanism

描述了一种基于消息机制构建的片上多处理器系统。该系统采用主从结构,运用消息进行通信,并且从处理器之间彼此相互独立,在硬件结构与软件设计上保持一致。这样不仅简化了系统的设计,更使得系统具有一定的容错性与稳定性。最后在Quartus软件中设计并且综合,在该系统下运行JPEG编码算法,当运行于100MHz时,测得系统在不同个数处理器时的处理性能,满足了设计要求。

In this paper, a multi-processor system on chip based on message mechanism is introduced. This system uses a master-slave structure, and message is used to communicate. Slave processors are independent from each other, and the hardware architecture and software design are the same. In this way, it not only simplifies the system design, but also makes the system a certain degree of fault tolerance and stability. Finally, this system is designed and integrated in Quartus. JPEG encoding algorithm is designed for this system. When this system runs at 50 MHz, the process performance in different number of processors is recorded, meeting the design needs.
