Abstract: 1,265,756. Storage control systems. GENERAL ELECTRIC CO. 6 June, 1969 [14 June, 1968], No. 28844/69. Heading G4C. A storage control system controls the transfer of data between a first memory 10 (Fig. 2) and second circulating store 12 having periodically accessible sectors 62 separated by normally unutilized guard bands 61 such that information may be additionally stored in and retrieved from the guard bands. To initiate transfer of data a processor executes a " connect " instruction to retrieve a peripheral control word from magnetic core memory 10 and enter it in extended memory controller 16. A decoder 42 receiving bits 18, 19 of the 36 bit peripheral control word feeds a signal to register 46 holding bits 0-17 of the word (that is the address in memory 10 of a data control word) so that the data control word at that address, comprising two 36 bit words, is read one word at a time into decoder 46. Each data control word comprises four parts-(a) the working store cell address of the information to be transferred, (b) the auxiliary store sector address of the information to be transferred, (c) the working store address of the next data control word to be retrieved and (d) a function portion. The latter signifies whether data is to be stored in or retrieved from magnetic disc or drum memory 12 and whether a " normal mode " or " mode 1 " operation is to be performed, i.e. whether sectors or guard bands are to be accessed. During " normal mode " operation blocks of 64 data words are transferred in blocks of four whilst during a " mode 1 " operation 8 data words are transferred. The function portion of the data control word is fed to decoder 46 controlling a main memory control 44, sync. control 48, write amplifier 68, track address selection matrix 50, data transfer control matrix 156 and mode control 43. To transfer data from memory 10 to memory 12, sync. control 48 compares the address of memory 12 as it rotates with the address of the data control word during which time four words are transferred into holding registers 174. At equality of address the contents of the registers 174 are transferred in parallel via gates 172 into shift registers 64, the contents of which are fed serially to write amplifier 68 to be entered into the memory. To transfer data from memory 12 to memory 10, sync. control 48 compares the addresses of the memory 10 and the data control word, at equality read amplifier 66 being enabled to serially read in four words to shift register 64. The contents of the register 64 are transferred in parallel to registers 174 and then to memory control 18 together with an address signal for storage in main memory 10.
