By duplicating the data stored in each set 17, 18 or 23, 24 a faster operating speed is attainable when interchanging the inputs 41, 42 to the arithmetic unit 10 (using switching logic 39). The register banks 17, 18 and 23, 24 are addressed by the same address on lines 33, 34 for updating and receive a data input from switching logic 32 which selects the source from a data bus 97, the direct output from the arithmetic unit 10 or the AU output shifted in either direction by registers 104, 105. The arithmetic unit 10 also includes flag registers 12, 13 for the interrupt Y and non-interrupt Y levels. A program store 50 is divided into two halves 82, 81 each of one word width and addressed by a respective program counter 51, 52 for the Y, #Y levels, the selected program counter supplying an address to both of a pair of address buffers 61, 62 to access a double width instruction word. The address supplied to buffer 61 may be incremented by circuitry 67, 72, 83 to ensure that the two words accessed are consecutive. The two words read out are gated in correct sequential order by a multiplexer 87 into buffers 92, 93. Jump instructions are of double length, the second half being a literal address value which is gated from buffer 92 directly into address buffers 61, 62 simultaneously with its loading into the appropriate program counter 51 of 52 to reduce the delay inherent in a program jump operation. The contents of the selected program counter 51, 52 or the address bus 68 may be gated to data bus 97 and via logic 32 and the register banks 17, 18 or 23, 24 to the arithmetic unit 10 for modification and then to the address buffers 61, 62 via a buffer 49. The instruction word in buffer 93 is decoded at 37 to control switching logic 32, 39, addressing of the register banks 17, 18 and 23, 24 and the arithmetic unit 10. The program store 50 may be loaded from magnetic disc files with programs for peripheral devices when the processor is used as an I/O controller. Buffers 49, 92 and 93 may be duplicated if interrupt is allowed during instruction execution.
