| Abstract(in English) | This paper presents FPGA-based implementation and performance analysis of the hardware for lossless compression of a floating-point data stream. The implementation includes the variable-to-fixed length converter (VF Converter) and the fixed-to-variable length converter (FV Converter). The prototype system on ALTERA Stratix IV FPGA demonstrates that the compressor and the decompressor are very small so that they each consume only 0.5 % adaptive LUTs of the total resource on the FPGA. The compressor and the decompressor can operate at about 240 MHz and 200 MHz. Such small but high-speed hardware modules can reduce the bandwidth by a factor of an average compression ratio. Evaluation with the computational results for 2D fluid simulation shows that the compressor has an average compression ratio of 3.7. This means that the compressor operating at 200 MHz can supply the bandwidth of 800 MB/s for single-precision floating-point numbers with the compressed bandwidth of 216 MB/s. |
