Frame buffer compression
Maturity plannedTargets FPGA + ASICDifficulty HardPriority 2
Lossless tile-based frame buffer compression and decompression to reduce memory bandwidth between graphics, video and display.
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 |
| pix_in | in | AXI4-Stream | 64 | |
| comp_out | out | AXI4-Stream | 64 |
