Wi-Fi lower-MAC assist
Maturity plannedTargets FPGA + ASICDifficulty HardPriority 3
802.11 lower-MAC hardware for SIFS-timed ACK/BlockAck, EDCA backoff, A-MPDU aggregation and deaggregation, beacon TSF and FCS, under a software upper MAC.
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

|---|---|---|---|---|
| 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 | AXI4-Stream | 32 | |
