Title: Craig Mudge: Processor and Control-Store Innovations

Introduction

Craig Mudge is an inventor associated with Weston, Massachusetts, and Digital Equipment Corporation. His work includes patents concerning processor architecture and the control stores used to manage data-processing systems. His recorded portfolio includes 2 patents.

Latest Patents

Mudge’s listed patents address complementary aspects of processor control and data transfer.

“Processor for a Data Processing System” describes a processor made up of functional units connected by a data bus. A control store holds microprogrammed instructions that direct the units’ operation, while a secondary control store holds selected instructions for transfers between units. Logic within the units decodes those instructions and connects the appropriate apparatus to the bus.

“Writeable Control Store for Use in a Data Processing System” describes a store that can operate in two modes. In one mode, it supplies instructions that control the processor. In the other, data can be written to or retrieved from the store, with a secondary control means managing those transfers.

Career Highlights

Mudge’s listed work at Digital Equipment Corporation reflects an interest in the mechanisms that coordinate processor operations. The patents focus on microprogrammed control, communication among processor units, and flexible access to writable control storage.
