FIELD: computer engineering. SUBSTANCE: program memory has vector memory area wherein initial addresses of library programs are entered as carry goals (vectors 1050, 3000). Library program is invoked by specifying vector number (0 through n) used by memory control unit to identify respective address in vector memory. Microprocessor incorporates provision for its protection against manipulations during access to library programs through users' programs. EFFECT: enhanced reliability of microprocessor protection against manipulations. 8 cl, 3 dwg
