Accommodating memory latency in a low-cost rasterizer

This paper describes design tradeoffs in a very low cost raster&r circuit targeted for use in a video game console. The greatest single factor affecting such a design is the character of memory to which the image generator is connected. Low costs generally constrain the memory dedicated to image generation to be a single package with a single set of address and data lines. While overnll memory bandwidth determines the upper limit of performance in such a small image generator, memory latency has n fnr greater effect on the design.
