带宽压缩通过提高有效带宽来提高流计算的性能。为了将带宽压缩应用于诸如数值模拟的数值应用，压缩器必须处理多个数据流。在本文中，我们描述了一个基于FPGA的高性能流计算的带宽压缩器的设计。针对不同码率的多个压缩流中原始数据的同步问题，提出了一种数据块传输调度器，并探索了减小桶形移位器尺寸的设计空间。
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.
