The TMS34020 and the TMS34020A graphics processors are 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 TMS34020 and TMS34020A provide 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.
The information contained in this data sheet is applicable to both the TMS34020 and the TMS34020A, except that pertaining to clock stretch, which begins on page 21. Use of the term TMS34020 shall refer to both devices except where noted.
