ZipAccel-C is a custom hardware implementation of a lossless data compression engine that complies with the Deflate, GZIP, and ZLIB compression standards.
The core receives uncompressed input files and produces compressed files. No post processing of the compressed files is required, as the core encapsulates the compressed data payload with the proper headers and footers. Input files can be segmented, and segments from different files can be interleaved at the core’s input.
The core’s flexible architecture enables fine-tuning of its compression efficiency, throughput, and latency to match the requirements of the end application. Throughputs in excess of 100 Gbps are feasible even in low-cost FPGAs, and latency can be as small as a few tens of clock cycles.
ZipAccel-C offers compression efficiency practically equivalent to today’s popular deflate-based software applications. Analyzing processing speed versus compression efficiency to achieve the best trade off for a specific system is facilitated by the included software model, and by support from our team of data compression experts.
ZipAccel-C has been designed for ease of use and integration. It operates on a standalone basis, off-loading the host CPU from the demanding task of data compression, and optionally from the task of encrypting the compressed stream. Streaming data interfaces and optional AMBA bus interfaces ease SoC integration.
Technology mapping is straightforward, as the design is scan-ready, microcode-free, and uses easily replaceable, generic memory models. Memory blocks can optionally support Error Correction Codes (ECC) to simplify achievement of Enterprise Class reliability requirements. Furthermore, input file segmentation can limit the inter-file latency and helps users achieve Quality of Service (QoS) objectives. The core has been rigorously verified and production proven in numerous commercial products.
