HDMI 2.1 transmitter controller
Maturity plannedTargets FPGA + ASICDifficulty Very hardPriority 2
HDMI 2.1 source controller with TMDS and FRL modes up to 12 Gb/s per lane, packetisation of video, audio and InfoFrames, DSC transport and SCDC.
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 |
| video | in | AXI4-Stream | 144 | |
| audio | in | AXI4-Stream | 32 | |
| phy_tx | out | parallel | 160 |
Standards
- HDMI 2.1b
- VESA DSC 1.2a
Notes
HDMI adopter agreement required before tape-out.
