LZ4SNP-D is a custom hardware implementation of a lossless data decompression engine for the LZ4 and Snappy compression algorithms. The core receives compressed files, automatically detects the LZ4 or Snappy format, and outputs the decompressed data.
The core features fast processing with low latency and high throughput. In its default configuration, LZ4SNP-D outputs up to 7.8 bytes of decompressed data per clock cycle and can be clocked at frequencies exceeding 1 GHz in modern ASIC technologies. Designers can scale the throughput by instantiating the core multiple times to achieve throughput rates exceeding 100Gbps. The processing latency is approximately 30 clock cycles.
The decompression core operates on a standalone basis—offloading the host CPU from the demanding task of data decompression—and has been designed for easy integration and use. No preprocessing of the incoming compressed files is required, as the core parses the file headers, chec...

The decompression core operates on a standalone basis—offloading the host CPU from the demanding task of data decompression—and has been designed for easy integration and use. No preprocessing of the incoming compressed files is required, as the core parses the file headers, checks the input files for errors, and outputs the decompressed data payload.
Extensive error tracking and reporting enable the core to ensure smooth system operation and error recovery, even in the presence of errors in the compressed input files. Furthermore, internal memories can optionally support Error Correction Codes (ECC) to simplify achieving enterprise-class reliability or functional safety requirements.
