Programmed digital computer system - has three data buses each comprising several data memory circuits, one for each digit in computer

摘要

The buses(3, 6, 7) transfer operands, instructions, intermediate and final results between respective inputs and outputs of a data memory(9) for storing data for the period of executing one instruction. It also has a program memory(1), a control unit(8), a control register unit(10), a computing unit(11), a data shifter(12), a masking unit(13) a data address unit(14), a data receive and transfer unit(15) and a instruction address unit(16) which generates the address of the next micro instruction. A control data memory(18) is connected to the other units and a data analysis bus(30). Pref. this increases the operation speed of the system and reduces the amount of hardware.
