Parametric equaliser
Maturity plannedTargets FPGA + ASICDifficulty EasyPriority 1
Cascaded biquad filter bank with programmable coefficients per channel for parametric and graphic equalization.
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 | APB 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 |
Standards
No external standard applies.
