of_hash_lookup
Hash table lookup engine
Maturity plannedTargets FPGA + ASICDifficulty HardPriority 3
Exact-match hash table in SRAM with configurable hash (CRC or Toeplitz), multi-way buckets, cuckoo insertion and lookup pipeline.
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 |
| key | in | AXI4-Stream | 128 | |
| result | out | AXI4-Stream | 64 |
Standards
No external standard applies.
