The 34010 Graphics System Processor is a 32-bit graphics microprocessor capable of executing high-level languages. It combines a full general-purpose instruction set with a powerful set of graphics instructions that includes arithmetic as well as Boolean pixbits (pixel block transfers). Because it is completely programmable, the 34010 can be used in many different graphics and nongraphics applications. it was designed to support a wide range of display resolutions and pixel sizes, as well as applications such as page (laser) printers, ink jet printers, data compression, and facsimile transmission. The 34010 includes such system features as an on-board instruction cache, full interrupt capability, wait and hold functions, and display timing control, as well as test and emulation support. Unique among today's microprocessors, the 34010 addresses all memory down to the bit level with variably sized fields rather than the common byte or word addressing. For example, the 34010 can push a 5-bit quantity onto a stack. This field-processing capability is an integral part of the basic architecture.
