The prototype also leaves room for future performance improvements, which could improve the accelerator to eliminate this slightly decreased compression ratio. Simulation results show that the hardware accelerator is capable of compressing data up to 100 times faster than software, at the cost of a slightly decreased compression ratio. Download scientific diagram 5: Input/output file of Snappy compression from publication: An FPGA-based Snappy Decompressor-Filter New interfaces to. ![]() A working prototype of the compression accelerator is designed and programmed, then simulated to asses its speed and compression performance. 1 Answer Sorted by: 2 You are compressing the plain string, as the compress function takes raw data. For example, running a basic test with a 5.6 MB CSV file called foo.csv results in a 2.4 MB Snappy. Google created Snappy because they needed something that offered very fast compression at the expense of the final size. LZMA is supplied by 7-Zip on ultra compression. Google Snappy, previously known as Zippy, is widely used inside Google across a variety of systems. This work explores the possibility of using dedicated hardware to accelerate the same general-purpose compression algorithm normally run at the warehouse-scale computer level. Deflate is supplied by 7-Zip on ultra compression. ![]() In the exa-scale age of big data, file size reduction via compression is ever more important.
