Union-find surface code decoder
Maturity plannedTargets FPGA + ASICDifficulty HardPriority 1
Streaming union-find decoder with cluster growth and peeling for surface code syndromes, sized for real-time decoding of each round.
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 |
| syn_in | in | AXI4-Stream | 256 | |
| corr_out | out | AXI4-Stream | 256 |
Standards
No external standard applies.
