Zstandard decompressor
Maturity plannedTargets FPGA + ASICDifficulty Very hardPriority 3
Zstandard frame decompressor with FSE and Huffman entropy decoding, sequence execution and configurable window size.
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 |
