LZ77 match finder with hash chains and Huffman encoder producing raw DEFLATE, zlib or gzip streams.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
Interfaces
| Port | Direction | Kind | Width | Notes |
|---|---|---|---|---|
| ctrl | in/out | AXI4-Lite control bus | 32 | Control and status registers, including ID, VERSION and STATUS |
| irq | out | interrupt | 1 | Interrupt request |
| raw_in | in | AXI4-Stream | 128 | |
| cmp_out | out | AXI4-Stream | 128 |
Standards
- RFC 1951 (DEFLATE)
- RFC 1950 (zlib)
- RFC 1952 (gzip)
