Single chip magnetic bubble processor

Abstract

A magnetic bubble processor comprising components for causing the movement of magnetic bubbles and a single chip having a layer of magnetic material in which magnetic bubbles can be moved. The chip comprises an input circuit for conveying electrical data and instructions into the processor and a generator responsive to the input data and instructions for producing magnetic bubbles representing bits of information. Paths are provided on the chip for routing magnetic bubbles within the processor as well as a memory organization accessible for the storage and retrieval of magnetic bubble information. The chip also includes magnetic bubble logic for performing mathematical operations and for providing magnetic bubble output information representing the results thereof. Further, the chip includes a magnetic bubble decoder for deciphering information and providing magnetic bubble output signals determinative of operations the processor is to perform and a magnetic bubble circuit responsive to the decoder output signals for controlling the routing of magnetic bubble information along predetermined paths within the processor, the storage and retrieval of information in the memory, and for instructing the logic as to which mathematical or logical operations are to be performed. A magnetic bubble detector on the chip converts the output of the logic from magnetic bubble information into discrete processor electrical output signals. The converted information is conveyed out of the processor by an output circuit on the chip. Thus, complex programs involving mathematical and logical operations using magnetic bubble data and instructions may be performed on one chip with a minimum of external circuitry and control required.
