1. Microprocessors I Why study Microprocessors? –Why not use PLD/FPGA designs for all digital designs What are microprocessors? How do they work? How do they interface to external (or internal) peripherals? What are the internal components? Why study the 8086?

3. Microprocessors versus ASICs COST AND TIME!!! –Microprocessor based designs can be much less expensive UNLESS Many parts are being manufactured (>100,000) Time is not crucial (design, manufacture and test time for ASICs is much greater than for micros)
