ABSTRACT:
A computer controlled apparatus includes a program counter for manifesting program count values and a processor for executing a prestored program in accordance with the program count values. The apparatus includes a read only memory with a prestored program that is accessible in response to generation of a span of program count values. Auxiliary memory includes a prestored program segment. A control circuit is coupled to the program counter and stores a predetermined program count value within the span of program count values in ROM. The control circuit is responsive to a match of a program count value from the program counter and the determined program count value to cause the program counter to be loaded with a branch program count value. That value enables the processor to immediately access and execute the prestored program segment from the auxiliary memory in lieu of a subspan of program count addresses in the ROM. The processor responds to the branch program count value as though it is a next program count value from a previous program count value, thereby seamlessly executing the second prestored program.
