ABSTRACT:
A processor arrangement consists of a number of individual autonomous processor units which communicate with each other by means of electro-magnetic waves. The electro-magnetic energy is typically at infra-red optical frequencies. Although the energy necessary to operate the individual processor units can be supplied by means of conductive bus bars, in a preferred arrangement the energy is supplied from a light source at optical frequencies to photo cells mounted on each of the processor units. Each processor arrangement is provided with an input-output device which communicates with the individual processor units by means of electro-magnetic waves and is provided with external conductive leads in a conventional manner. The whole processor arrangement is encapsulated in an evacuated chamber.
