High-speed access to stored data using switched memory decoding

Abstract Microprocessor systems used in realtime instrumentation and control applications must scan and process a large quantity of empirical data at high speed. When sets of data from a number of successive scans must be stored and processed the time involved in accessing the data by normal methods can be unacceptably long. This paper describes the design of a switched memory decoding circuit which allows data of this type to be accessed at high speed. The way in which the circuit is incorporated in a memory management system for this type of application is also considered.
