ZipAccel-D is a custom hardware implementation of a lossless data decompression engine that complies with the Inflate/Deflate, GZIP/GUNZIP, and ZLIB compression standards.The megafunction features fast processing, with low latency and high throughput. On average the megafunction outputs two bytes of decompressed data per clock cycle, providing over 5Gbps in a typical 40nm technology. Designers can scale the throughput further by instantiating the megafunction multiple times to achieve throughput rates exceeding 100Gbps.The latency for blocks coded with Static Huffman is in the order offew tens of clock cycles, and blocks coded with Dynamic Huffman get processed in lessthan 1500 cycles.
Latency from a 20 clock cycles for Static Huffman blocks, and less than 1500 cycles for Dynamic Huffman Blocks
Up to 32KB history window size; All deflate block types
Throughputs exceeding 2Gbps in most FPGAs with a single core, and scalable to more than 100Gbps with multiple core instances
ZipAccel-D reference designs have been evaluated in a variety of technologies. ZipAccel-D performance can scale by instantiating more Huffman decoders and by using multiple megafunction instances. The core configured with Static Huffman only uses 2,281 ALMs and 20,160 RAM bits in an Intel® Arria® 10 device.
