1953Wilkes & Stringer in Proc. Cambr. Philos. Soc. XLIX. 230 The operation called for by a single machine order can be broken down into a sequence of more elementary operations... These elementary operations will be referred to as micro-operations. Basic machine operations, such as addition, subtraction, multiplication, etc., are thought of as being made up of a micro-programme of micro-operations, each micro-operation being called for by a micro-order. 1962Huskey & Korn Computer Handbk. xvi. 32 Once a given set of instructions has been designed into the machine by the wiring of a microprogram plugboard, the machine may be used as a stored-program computer in the normal fashion. 1969[see microprogrammed ppl. a.]. 1971New Scientist 7 Jan. 27/1 This memory can hold up to 1024 words of microprogram which can be changed easily and inexpensively and tailored exactly to suit individual requirements. |
