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?

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)

Books for the Course K. Irvine, Assembly Language for Intel- Based Computers, Fourth Edition, Prentice Hall, J. Uffenbeck, The 80x86 Family – Design, Programming, and Interfacing, Third Edition, Prentice Hall, 2002.

How will you this material? Pick up a microprocessor book!!! Know where to look for more information!!! –For the 80x86 family Know that all microprocessors are in some ways similar – Typically used for controlling peripherals
