Multi-applications mapping platform based on hardware and software

Abstract

The mapping problem of the NoC (Network on Chip) is NP-hard, each mapping algorithm has its disadvantages for different applications. Traditionally, mapping algorithms verification are based on the software, such as Noxim, which is too slow for large scale NoC emulation. For the reason, we propose a NoC mapping platform and an emulation system with virtualization technology based on FPGA. The experiment show that, the platform can select appropriate mapping algorithms for multi applications, and map-ping algorithm can be improved by the feedback emulation result. Using virtualization technology, the Mesh NoC with 72 node consume only 14% hardware resource on xc7k325tf-fg900-2. We implement the SCPU to generate the data characteristic of the application being mapped with only 2% resource overhead.
