WebG.R. Wilson, in Embedded Systems and Computer Architecture, 2002. 13.3 Instruction fetch. The first byte of an instruction is the operation code, which indicates what the instruction is to do. Thus, the first step is to read the operation code into the Instruction Register, IR, of the G80. This step is called the instruction fetch. http://viennaict.weebly.com/uploads/1/6/6/4/16648014/chapter_3_von_neumanns_architecture.pdf
