This paper describes a programmable pixel processor, the SX, that has been implemented in the memory controller chip of a workstation. 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 accelerators, at the lowest possible cost. The SX is 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 about 400 megabytes in size. The SX offers a cost-effective method of providing graphics and image processing capability compared to traditional workstation and accelerator approaches.
