The widespread use of microprocessor systems in science and technology has led to an unprecedented increase in their production abroad and in our country. Therefore, traditional methods of design and debugging have become replaced by machine methods. This monograph by a famous American author is one of the first in this important direction. It discusses modern microcomputer design systems with an illustration of specific examples. Much attention is paid to the description of Intel, Motorola, Zilog microprocessors, as well as related software. To select the type of high-level language, comparative data on the languages ​ ​ Basic, Fortran, PL-1, Pascal and Kobol are given. The monograph can be used as a reference manual for hardware and software microprocessors. In the Russian translation comes out in two books. For computer engineers and computer students.
