Bandwidth compression improves the performance of stream computing by enhancing an effective bandwidth. To apply the bandwidth compression to numerical applications such as numerical simulations, a compressor has to handle multiple data streams. In this paper, we describe a design of an FPGA-based bandwidth compressor for high performance stream computation. For synchronization of original data in multiple compressed streams with different bit-rate, we propose a data block transmission scheduler and explore a design space to reduce the size of their barrel shifters.
