Audio DSP core
Maturity plannedTargets FPGA + ASICDifficulty HardPriority 2
Low-power DSP with 24/32-bit fixed point and single-precision floating point MACs, audio sample I/O ports and always-on operation for voice and audio pipelines.
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 |
| pcm_in | in | AXI4-Stream | 32 | |
| pcm_out | out | AXI4-Stream | 32 |
