Xlinx LZ4 Streaming Compression

LZ4 Compress Streaming example resides in L2/tests/lz4_compress_streaming directory.

Follow build instructions to generate host executable and binary.

The binary host file generated is named as xil_lz4_streaming and it is present in ./build directory.

Executable Usage

  1. To execute single file for compression : ./build/xil_lz4_streaming -xbin ./build/xclbin_<xsa_name>_<TARGET mode>/compress_streaming.xclbin -c <input file_name>

  2. To execute multiple files for compression : ./build/xil_lz4_streaming -xbin ./build/xclbin_<xsa_name>_<TARGET mode>/compress_streaming.xclbin -cfl <files.list>

    • <files.list>: Contains various file names with current path

The usage of the generated executable is as follows:

Usage: application.exe -[-h-c-cfl-xbin-id]
       --help,                -h        Print Help Options
       --compress,            -c        Compress
       --compress_list,       -cfl      Compress List of Input Files
       --max_cr,              -mcr      Maximum CR                                            Default: [10]
       --xclbin,              -xbin     XCLBIN
       --device_id,           -id       Device ID                                             Default: [0]
       --block_size,          -B        Compress Block Size [0-64: 1-256: 2-1024: 3-4096]     Default: [0]
