Abstract
1,154,516. Shifting in a computer. GENERAL ELECTRIC CO. 23 May, 1967 [25 May, 1966], No. 23872/67. Heading G4A. In a computer system data from a selected one of a plurality of storage locations in a data storage unit is transferred to a register, and from there via shift means back to the selected storage location without passing through another register in the process. Peripheral sub-systems (input/output and storage) communicate via an input/output controller with main memories each associated with a respective processor. The input/output controller is controlled from one of the main memories selected manually and includes a micro-programme store, a processor and a buffer store. The buffer store includes two oneword buffers for each of six peripheral subsystems. During transfer of data from one of these sub-systems, a word is read from one of the buffers into a register and from there passed through shift logic which displaces (shifts) characters and associated parity (one per character) and count (one per character) bits to make room for a character received from the peripheral sub-system together with its parity and count bits which are gated in by the shift logic. The output of the shift logic is stored back in the buffer. Each count bit is ONE and when the first of these count bits reaches a given position during the shifting, the buffer is full. During transfer of data to one of the six subsystems, a word to be transferred is placed in the register referred to, one character being sent to the sub-system and the others being transferred, with a one-character shift, into one of the buffers. The buffer contents can then be read out into the register, one character sent to the sub-system and the rest returned to the buffer with a one-character shift, and so on. Transfer of the word is complete when a count bit, inserted in the buffer initially, reaches a particular position. Two buffers are also provided for each of the other peripheral subsystems, each holding one data character, a parity bit and a " count " bit.
