Evaluating Network-on-Chip for Homogeneous Embedded Multiprocessors in FPGAs

— This paper presents performance and area evaluation of a homogeneous multiprocessor communication system based on network-on-chip (NoC) in FPGA platforms. Two homogenous chip multiprocessor proposals were designed and compared for Xilinx FPGAs using MicroBlaze processors: one based on NoC and the other based on shared memory/bus. One of the main findings is the communication performance evaluation of NoC for parallel computing applications. The comparison results show that an efficient implementation of NoC on FPGA can improve communication speed by up to seven times with low area overhead, according to the data size and the number of processors connected to the network.
