DEFLATE / gzip compressor
Maturity plannedTargets FPGA + ASICDifficulty Very hardPriority 3
LZ77 hash-chain match finder with configurable window and search depth plus fixed or dynamic Huffman encoding, producing DEFLATE, gzip or zlib 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 |
| s_in | in | AXI4-Stream | 64 | |
| m_out | out | AXI4-Stream | 64 |
