The SMJ34020A graphics system processor (GSP) is the second generation of an advanced high-performance CMOS 32-bit microprocessor optimized for graphics display systems. With a built-in instruction cache, the ability to simultaneously access memory and registers, and an instruction set designed to expedite raster graphics operations, the SMJ34020A provides user-programmable control of the CRT interface as well as the memory interface (both standard DRAM and multiport video RAM). The 4-gigabit (512-megabyte) physical address space is addressable on bit boundaries using variable width data fields (1 to 32 bits). Additional graphics addressing modes support 1-, 2-, 4-, 8-, 16- and 32-bit wide pixels.
