MIPI SoundWire manager
Maturity plannedTargets FPGA + ASICDifficulty HardPriority 3
MIPI SoundWire manager for multi-drop audio links with frame shaping, bulk register access and isochronous audio channels to codecs and amplifiers.
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 |
| sw_clk | out | clock | 1 | |
| sw_data | inout | serial | 1 | |
| audio_tx | in | AXI4-Stream | 32 | |
| audio_rx | out | AXI4-Stream | 32 |
