Outline Design a processor: step-by-step Requirements of the Instruction Set Hardware components that match the instruction set requirements
How to Design a Processor: step-by-step 1. Analyze instruction set architecture (ISA) => datapath requirements
meaning of each instruction is given by the register transfers datapath must include storage element for ISA registers datapath must support each register transfer
2. Select set of datapath components and establish clocking methodology 3. Assemble datapath meeting requirements 4. Analyze implementation of each instruction to determine setting of control points that effects the register transfer. 5. Assemble the control logic
