The Structure of an Elementary Microcomputer

  • W. F. Stoecker
  • P. A. Stoecker


We define an elementary microcomputer as the assembly incorporating a microprocessor, ROM(s), RAM(s), and means to accomplish inputs and outputs. These components are connected through data and address buses. The elementary microcomputer can perform useful calculations, make decisions, and control small systems. The elementary microcomputer is representative of a small unit dedicated to controlling an individual machine or a small number of processes. Such a dedicated microcomputer would be assembled, programmed, and even mounted on the machine at the factory. If the user is expected to make frequent changes or adjustments to the program, the elementary microcomputer may be inadequate, and a higher-level computer should be considered.
