RESUMO

The design and realization of a microcomputer for high security level applications is described. Erroneous data transmission may be prevented by: -self - checking circuits -blocking the computer upon detection of a failure. The microcomputer is built around the Intel 8080 microprocessor and has the followinf characteristics: - All the working circuits are tested. - a card level dragnosis is provided with indication by panel of the faulty unit, atter computer stop. - memory detection by parity bits - 8 I/0 ports. An evaluation of the number of the envisaged memory is presented.
