USB 2.0 high-speed device controller
Maturity plannedTargets FPGA + ASICDifficulty MediumPriority 1
USB 2.0 HS/FS device controller with up to 16 endpoints, bulk/interrupt/isochronous transfers, DMA and a UTMI+ or ULPI PHY interface.
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 |
| utmi_tx | out | parallel | 10 | |
| utmi_rx | in | parallel | 12 | |
| ep_out | out | AXI4-Stream | 32 | |
| ep_in | in | AXI4-Stream | 32 |
