SAS-4 link and port layer
Maturity plannedTargets FPGA + ASICDifficulty Very hardPriority 3
SAS 24G link, port and transport layers with SSP/STP/SMP support, 128b/150b encoding and wide-port aggregation.
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 |
| phy_tx | out | parallel | 40 | |
| phy_rx | in | parallel | 40 | |
| frames | out | AXI4-Stream | 128 |
