Xilinx GZip Static Streaming Compression¶

GZip example resides in L2/tests/gzipc_static directory.

Follow build instructions to generate host executable and binary.

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

Executable Usage¶

To execute single file for compression : ./build/xil_gzip -xbin ./build/xclbin_<xsa_name>_<TARGET mode>/compress.xclbin -c <file_name>
To execute multiple files for compression : ./build/xil_gzip -xbin ./build/xclbin_<xsa_name>_<TARGET mode>/compress.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-B]
       --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]
       --zlib,                -zlib     [0:GZip, 1:Zlib]                                Default: [0]
