Reconfigurable Communication Networks in a Parametric SIMD Parallel System on Chip

Abstract

The SIMD parallel systems play a crucial role in the field of intensive signal processing. For most the parallel systems, communication networks are considered as one of the challenges facing researchers. This work describes the FPGA implementation of two reconfigurable and flexible communication networks integrated into mppSoC. An mppSoC system is an SIMD massively parallel processing System on Chip designed for data-parallel applications. Its most distinguished features are its parameterization and the reconfigurability of its interconnection networks. This reconfigurability allows to establish one configuration with a network topology well mapped to the algorithm communication graph so that higher efficiency can be achieved. Experimental results for mppSoC with different communication configurations demonstrate the performance of the used reconfigurable networks and the effectiveness of algorithm mapping through reconfiguration.
