Abstract
A color graphic processor includes one or more processing elements responsive to pixel data provided by a frame buffer. The processing element stores pixels from the frame buffer in source and destination registers. The arithmetic logic unit (ALU) portion of the processing element includes a random access memory (RAM) addressed by the registers to produce a result pixel value which can be written back to the frame buffer. The RAM can implement a wide variety of pixel operations by loading the RAM with operation specific data.
