Abstract

1411182 Digital computers STANDARD TELEPHONES & CABLES Ltd 4 Jan 1973 560/73 Heading G4A [Also in Division H4] A multi processor computer system, e.g. for controlling a telecommunication exchange, has processors CPU1-CPUn which can access any memory block M1-Mn, e.g. permanent or erasable, via memory control units MCUIMCUN, communicate with other parts of the system via the memory, and control channel multiplexor units CMUI-CMUn. A function and time allotter FTA (Fig. 2, not shown) produces clock interrupt signals which alter the allocation of tasks (e.g. programs for telephone calls) to the processors at frequent intervals and also when a fault develops in any processor, all processors being capable of handling any task. Alloter FTA has three replicated units each with a clock generator, a control unit and a microprogram memory holding the status of each CPU and two adjustable algorithms which control the time and reallocation functions. These units are connected via majority logic to the interrupt lines. Read/write of memory content or task reallocation can be effected by manual controls or by program, and the system state is shown on a display. Also provided are back up magnetic drum or disc memories MM, teleprinters or line printers SP, and diagnostic programs for hardware and software. When a unit is faulty the system is reconfigured and, when it has been repaired, the system is manually interrupted and diagnostic programs effected before it is returned to service.
