Abstract

See full text

Fault resilient or fault tolerant computers are produced by designating a first processor as a computing element, designating a second processor as a controller, connecting the computing element and the controller to produce a modular pair, and connecting at least two module pairs to produce a fault resilient or fault tolerant computer. Each computing element of the computer performs all instructions in the same number of cycles as the other computing element. The controllers provide input/output processings for the computing elements, as well as monitor their operations to detect errors, and control operation of the computing elements in response to the detected errors.
