Title: Data processing system
IPC: G06F13/42
Filed: 1971-04-19
Abstract: 1353995 Digital computers DIGITAL EQUIPMENT CORP 19 April 1971 [1 April 1970] 25971/71 Heading G4A A digital electric data handling system comprises a plurality of peripheral units 26, 28, a random access memory unit 24, a processor unit 22 and means for transferring data amongst them using a common bus 30. The Specification is similar to those of British Specifications 1,353,951 and 1,353,925 and the same as that of the divided out Specifications 1,354,089 and 1,354,090. Information comprising data or instructions can be transferred between any two units in the system, one unit (the master unit) controlling the transfer to the other unit (the slave) using synchronization signals from both units. The peripheral and processor units can be master or slave while the memory unit is always a slave. Using this arrangement the processor unit and each peripheral unit responds to the same instructions, each peripheral unit transfers data asynchronously with respect to the processor unit, direct transfers between a peripheral unit and the memory unit can be made independently of the processor unit, and preliminary operations required to transfer control to a peripheral unit occur simultaneously with other processor unit operations. Another unit can obtain system control by making a request for control which is honoured if it has sufficient priority, control being returned to the processor unit after it has completed its transfer. Transfers requiring processor unit operation are made after an instruction is processed and may divert the processor to an interruption routine when the processor is the master. The apparatus.-(a) Processor Unit (Fig. 2, not shown). This includes a register memory including a plurality of storage registers one of which acts as a program counter and another of which identifies contiguous memory locations; an arithmetic unit including an adder; a gating unit which can rotate or shift data; an interruption priority unit and a status register concerned with priority control. The processor unit can transfer data in a fetch cycle, an execute cycle or a term cycle (Figs. 6 to 8 respectively, not shown). (b) Memory Unit (Fig. 3, not shown). This is divided into groups of contiguous locations for storing related instructions in sequential order, and random locations. The addressing system is described in Specification 1,353,925. (c) Peripheral Unit (Fig. 4, not shown) this includes a peripheral control unit, an interruption control unit and address selection circuitry. It is connected to the multi wire bus 30, different wires of which are used for different purposes (Fig. 1). (d) Timing Unit (Fig. 9, not shown). This controls the operation of the processing unit. The operation of the system is described in considerable detail including one example in which the peripheral unit is an A-D converter. Other features mentioned include magnetic drums and discs, a core memory, teletypewriters, card punchers and readers, subtraction and branching operations.
