[0042] The specific embodiments of the present invention will be further introduced below in conjunction with the accompanying drawings.
[0043] In the embedded field, traditional control-intensive applications are gradually shifting to data-intensive applications, and the proportion of data calculation and processing is gradually increasing. In view of this feature, in the design of multi-core chips, (using DSP engine as an example) is to integrate several DSP (digital signal processor) engines in the same chip, relying on the on-chip data communication network to realize these DSP engines Data exchange between.
[0044] The data bus in the multi-core processor chip (or "multi-core chip") in the present invention is composed of a static routing bus and a dynamic routing bus. In terms of function division, the static routing bus is responsible for high-throughput data transmission, and the dynamic routing bus completes flexible control variable transmission. The static routing b...
