Title: Data processing equipment
Inventor: HOWELLS GEORGE ANEURIN
IPC: G06F11/14
Filed: 1964-11-16
Abstract: 1,106,689. Data processing equipment; error correction. STANDARD TELEPHONES & CABLES Ltd. 12 Nov., 1965 [16 Nov., 1964], No. 46533/64. Headings G4A and G4C. A digital electric data processing system includes a store, an address decoder, a register for holding an address to be decoded, a matrix of switches controlled by the decoder for routing access currents to the required store location, means for detecting an error in the address register or in the matrix, means for providing an alternative address and means for selecting the same store location via the alternative address and an alternative current route. As described the address is accompanied by an error detection and correction code such as Hamming code and an error found in the address causes all the correct bits of the address to be complemented and applied to a second decoder and a second matrix of switches coupled in parallel to corresponding switches in the other matrix to provide a common access to the store. If some of the switches or pulse generators are faulty, an encoder or, alternatively, a current measuring circuit may be used to detect abnormalities and cause the complementing of the address. The address register may be buffered by two inverters in series (Fig. 8, not shown), and the signals applied to the decoders being derived from the inverters, a Hamming check being taken on the outputs from the first inverter. A further correction device is to check that one and only one output is derived from the decoder, no outputs or two or more outputs generally indicating a decoder fault or an inverter fault, which can be corrected by transferring to a complemented address and the other decoder and matrix assuming that only one error exists at any one time.
