Abstract
A method and system for accelerating graphics images in a computer system comprises encoding a first value information into an address signal from a CPU within the computer system and then encoding a second value information into the data signal from the CPU within the computer system. By encoding the information in this manner the location of the graphics data is unimportant. Hence, an address space of the memory can be utilized as the accelerator. In one aspect of the present invention, a span of a particular scan-line can be encoded in the address signal and the row and color information of the scan-line can be encoded in the data signal. In another embodiment, the span of a particular scan-line can be encoded in the address signal and the row, color information and intensity value information can be encoded into the data signal. The method and system uses to advantage that the main memory of the computer system has a large area which can be configured as an addressable space when rendering graphic images. Accordingly, graphics images can be rendered more quickly with minimal additional software and hardware overhead.
