GZIP Lossless Data Compression

Reduce data storage and bandwidth requirements

CAST offers a family of silicon IP cores for GZIP/ZLIB/Deflate lossless compression and decompression.  The IP cores of the family are highly configurable to allow fine-tuning of its compression efficiency, throughput, size and latency to match the requirements of the end application. These IP cores can be mapped in ASIC or FPGA, and have been used to reduce the cost and power for data storage and transfer within SoCs, as well as in big-data servers.

ZipAccel-C

  • GZIP, ZLIB, and Deflate compression
  • Highly configurable core allows different levels of compression efficiency, throughput, latency and size for different configurations
  • Capable of 100Gbps+ & gzip -6 compression level

ZipAccel-D:

  • Decompression of GZIP, ZLIB, and Deflate files
  • Limited versions allow optimizing area and/or latency
  • Scalable throughput by multiple core instantiations

Read about them below, see each core's product page, and contact Sales to learn more or discuss how we can support your evaluation.
 

iot architecture with gzip ip cores

Compression can be used to significantly reduce the energy consumption related to the power-hungry NVM and RF module of your design:  

  • NVM: Storing compressed (instead of uncompressed) firmware and decompressing on-the-fly at boot time reduces boot/wake-up energy and time.
  • RF: Transmitting compressed (instead of uncompressed data) over your RF link, reduces the active time for your RF front-end, and the energy related to it.
