Abstract
Invenţia se referă la tehnica de calcul şi microelectronică şi poate fi aplicată în plăci intelectuale pentru testarea informaţiei înregistrate în memorie unificată cu un microprocesor.Metoda include compararea informaţiei la ieşire din memorie (2), debitate prin canalul de citire (10), cu semnalele datelor prestabilite, generate din afară, şi debitate prin port (7) prin canalul de citire (9). Compararea se realizează cu ajutorul dispozitivului de comparare (3), care poate fi, de exemplu, un microprocesor programat pentru efectuarea comparării. La ieşirea dispozitivului de comparare (3) apare un semnal simplu de verificare, lansat la port (5). Datele păstrate, înregistrate în memorie (2) se pot păstra permanent în memorie, de exemplu, într-un dispozitiv cu memorie constantă (ROM) sau (dacă memoria se modifică în mod electric) pot fi înregistrate special în memorie pentru testare.Rezultatul constă în protecţia conţinutului memoriei de la accesul direct.
