Abstract
An improved microcomputer has a page register connected to a program counter in order to extend the program address range of the microcomputer. A page stack is connected to the pager register and operates in conjunction with an address stack. The page register is loaded from bits in the first word of a two word branch or call instruction in such a manner that no additional execution time is required nor are any additional instructions required to provide the extended address range. A predefined microprocessor ASIC cell is augmented by externally connecting a page register and an opcode decoder so that instruction memory address range can be expanded by paging without redesigning the microprocessor cell.
