Abstract
An MOS/LSI Number Oriented Processor is provided which is intended for number processing applications. The single chip device provides arithmetic, logarithmic and transcendental functions, test and branch capability, internal number storage and input/output capability. The Number Oriented Processor uses ROM library means to store routines for performing the required functions. The desired function is selected from the library by macro instruction means from an external ROM, RAM or microprocessor. The Number Oriented Processor can be used as a stand-alone processor with external ROM/PROM (or RAM) and program counter; or, it can be configured as a peripheral device on the bus of a microprocessor or minicomputer.
