CHI-style coherent mesh interconnect
Maturity plannedTargets FPGA + ASICDifficulty Very hardPriority 3
Scalable mesh of crosspoints with home nodes, distributed snoop filters and system cache slices implementing a CHI-style coherence protocol.
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 |
| rn_ports | in | valid-qualified bus | 512 | |
| sn_ports | out | valid-qualified bus | 512 |
