Abstract
The present invention is a programmable data processing system and apparatus which operates as an independent microprocessor. The programmable data processing system of the present invention stores both general purpose and special purpose graphic instructions. The programmable data processing apparatus of the present invention has both types of instructions within its instruction set. This provision of a single processing apparatus for preforming both types of instructions enables a highly flexible solution to bit map graphics problems. This is because the program of the data processing apparatus may be altered to provide the most desirable graphics algorithm without loss of the general purpose calculation and program flow capability of a general purpose data processor. The data processor of the present invention may serve as a parallel processor for a host data processing system for primarily control of bit mapped graphics. In addition this same type data processing apparatus may serve as an independent microprocessor within a single user computer or graphics terminal.
