ABSTRACT:
An electronic digital processor fabricated on a single MOS/LSI semiconductor chip includes an arithmetic unit operating on digits one at a time, with a carry output and a carry input. Commands for operating the processor are produced by decoding instruction words one at a time from a large instruction memory. A special status circuit is responsive to commands from instruction words to operate in several conditional modes. A carry input to the arithmetic unit is generated in response to whether carries were generated in either the current or previous digits being processed. Another status circuit provides the input for a conditional branch or call depending on whether a carry or compare logic signal is applied to the status circuit.
