The Digital Blocks DB9100AXI4 BitBLT Graphics Hardware Accelerator Verilog IP Core renders a graphics frame by generating new bitmaps from commands to combining existing bitmaps on and off-screen using one of 256 Raster Operations. A Raster Operation (ROP) is a bitwise Boolean operation (such as AND, OR, XOR, NOT).
The DB9100AXI4 also contains a Monochrome Bitmap Color Expansion feature, typically used for font expansion of compressed character bitmaps. A 1-bit depth bitmap is expanded to one of two colors, a foreground or background color, with the foreground color representing the text, and the background color the non-text background.
The DB9100AXI4 also contains a programmable Alpha Blend unit, blending two bitmaps into one.
The DB9100AXI4 interfaces to a microprocessor and frame buffer memory via the AMBA AXI4 Interconnect, providing high performance memory throughput. The DB9100AXI4 contains a DMA Command Linked-List Processing Unit, for independently reading and processing graphics commands from the host processor.
