Abstract
This paper is concerned with the hardware and architecture of microprogrammed equipment intended primarily for real time signal processing applications. Principles and structural types are discussed rather than a specific structure. There are numerous advantages to microprogrammed as contrasted to hardwired signal processing equipment. People in different positions view microprogramming as having different advantages. This paper presents some of these advantages together with hardware structure, microinstruction format, diagnostic techniques for both hardware and software, and various methods of control of a microprogrammed processor.
