A memory controller with an integrated graphics processor

The paper describes the SX graphics accelerator. It is a programmable processor built into a workstation memory system. The goal of the SX is to achieve performance comparable to that of low end 2D and 3D graphics processors and to surpass low end imaging performance, at the lowest possible cost. The SX contains an integer vector processor, with an instruction set tailored to the needs of image processing and multimedia as well as 2D and 3D graphics. It can directly access data in both video and main memory, allowing accelerated processing on images up to 512 Mbyte in size. The SX offers a cost-effective method of providing a rich graphics and image processing capability compared to traditional workstation and accelerator approaches
