There is nO' dDubt that the mioroprooessor (~p) revDlutiDn will cDntinue intO' the future and many will be required to' specify and integrate mi- crDprDceSSDrs intO' prDducts Dr systems in their Dwn disciplines. There- fDre, well-designed flexible interfaoes will be required to' ensure CDm- patibility with Dther equipments and to' extend design DptiDns. AlthDugh there are several bDDks Dn micrDcDmputers and micrDprDcessDrs, Dnly few Df thDse devDte but a small part Dn the impDrtant aspects Df interfaces. It was with this in mind that the present bDDk was written as a selfcDn- tained vDlume to' be part Df the mDre general series : Mioroprooessors- Based Systems Engineering. It fills an existing gap in technDIDgy, as in- terfaces are the last items to' be seriDusly cDnsidered in the race Df new technDIDgy, and it deals with the systematic study Df micrDprDcessDr interfaces and their applicatiDns in many diversified fields. This bDDk is aimed at engineers in industry and engineering stu- dents whO' need to' learn hDW to' interface micrDprDcessDrs, and hence mi- crDcDmputers and Dther related equipments, to' external digital Dr analDg devices. It is suitable fDr use as a textbDDk Dr fDr supplementary read- ing, either in an applied undergraduate CDurse in electrical engineering Dr in the last year Df three-year-curriculum technical cDlleges.
