Abstract

The invention discloses a PowerPC based multi-processor communication architecture. The PowerPC based multi-processor communication architecture comprises a main processor PowerPC, a plurality of secondary processor units and a plurality of remote control computers. The PowerPC based multi-processor communication architecture has the advantages that the data can be transmitted between different processor units at different transmission speed through different communication interfaces; the main processor module and the secondary processor modules are clear in division of work, the processing is fast, and the processing capacity is high; in addition, all modules can be manufactured into daughter cards, and therefore, the modularization and engineering of the multi-processor communication architecture can be achieved.

Description

Technical field [0001] The present invention proposes a multi-processor communication architecture based on PowerPC, which realizes data exchange between different communication interfaces, different transmission speeds, and different slave processors, and different slave processors communicate with the master processor PowerPC through the PCI bus. Data exchange has improved the transmission speed and processing capabilities between different processors. This PowerPC-based multi-processor communication architecture can be used in aerospace, industrial automation, machinery manufacturing and other fields. Background technique [0002] With the continuous development of science and technology, remote communication control has been widely used in aerospace, industrial automation, machinery manufacturing and other fields. However, remote control of data transmission between multiple processors and different communication interfaces is a difficult point in today's technology. [0003] ...
