Display Controller - LCD / OLED Panels (AXI Bus)

The DB9000AXI3 Display Controller IP Core interfaces a microprocessor and frame buffer memory via the AMBA AXI Protocol Interconnect to a LCD or OLED display panel.

The Display Controller Verilog RTL IP Core comes in releases supporting baseline display processing features and releases with advanced display processing, such as Multi layer Overlay Windows with optional Alpha Blending, Scaling, Color Space Conversion, 4:2:0 and 4:2:2 YCrCb with Re-sampling & conversion to RGB, and Hardware Cursor and Frame Buffer Compression. Optional features provide the customer with targeted features while saving on VLSI resources and licensing costs.

The DB9000AXI3 contains a selectable 256 / 128 / 64 / 32-bit AXI Master Interface with the higher data widths targeting higher resolution, higher color depth LCD or OLED display panels, with their resulting high frame buffer memory data bandwidth requirements.

The DB9000AXI3 IP Core can be implemented in an ASIC, ASSP, or FPGA device with an embedded microprocessor, an AMBA AXI Interconnect fabric, and SDRAM Controller for access to frame buffer memory. Typically, the microprocessor is an ARC, ARM, Intel, MIPS, OpenSPARC, PowerPC, RISC-V, or Tensilica processor and frame buffer memory is off-chip DDR 1-5 SDRAM.
