Abstract

Dispozitivul conform inventiei, utilizabil pentru conectarea echipamentelor periferice complexe la un microcalculator cu magistrala unica, avînd la baza o solutie microprogramata, se caracterizeaza prin aceea ca transferul informatiei între microprogramator, se caracterizeaza prin aceea ca transferul informatiei între microcalculator si echipamentul periferic este controlat de catre un procesor intern dedicat functiei de conectare, care asigura accesul rapid, de pe magistrala unica, a registrelor de interfata specializate pentru controlul dispozitivului, prin amplasarea acestora într-un fisier dubu-acces, componenta încorporata atît procesorului intern, ca set de registre de lucru, cît si interfetei cu magistrala unica, ca set de locatii cu adrese de memorie, fisierul închizînd astfel doua bucle de acces simultan, independent si în orice moment de timp, eliminînd necesitatea ciclurilor suplimentare de magistrala unica pentru accesarea propriilor registre, atunci cînd acestea sînt pastrate în memoria peincipala sau în originale si în copie (în dispozitiv) si asigurînd, totodata, mentinerea compatibilitatii cu software-ul existent.The device according to the invention useful for connecting complex peripheral equipment to a single bus microcarrier based on a microprogrammed solution is characterized in that the transfer of information between the microprogrammer is characterized in that the transfer of information between the microcomputer and the peripheral equipment is controlled by an internal processor dedicated to the sign-in function that provides fast access from the single bus to the device-specific interface registers by placing them in a dub-access file, the built-in component to the internal processor as a set of workbooks , as well as the single bus interface as a set of locations with memory addresses, thus closing the two access loops simultaneously and independently at any time, eliminating the need for additional single bus cycles to access their own registers when these to be kept in the original memory or in the original and in the copy (in the device) while ensuring the compatibility with the existing software.
