Title: Data storage apparatus
Inventor: LUCKING JAMES ROBERT
IPC: G06F12/122
Filed: 1964-12-17
Abstract: 1,124,017. Data store arrangements. ENGLISH ELECTRIC COMPUTERS Ltd. 16 Dec., 1965 [17 Dec., 1964], No. 51476/64. Heading G4C. Data storage apparatus comprises a main store 5 of relatively large capacity but slow access speed and a subsidiary store 6 of smaller capacity but higher access speed, the arrangement being such that recently accessed data in the main store is repeated in the subsidiary store at locations selected by a cyclic scanning means so as to be available in response to subsequent requests at short access times. In the arrangement shown, whenever a storage location in store 5 is accessed, the data group together with its address in the main store is stored in one of the 32 storage locations in store 6. On receiving a request signal at input unit 13, the requested address is stored in comparison unit 16 and a scanning device 17a is operated to scan all the addresses B0-31 in the store 6 to see if the requested data group is stored therein. If no equality is found, then main store 5 is accessed in the conventional way and the requested data group is read-out via line 9 and control unit 7 to data transmitting unit 11. At the same time the address of the requested data group is passed to the control group 7, from where, together with the data group, it is written into a vacant storage location as selected by scanning device 21A. If equality is obtained between the requested address in unit 16 and one of the addresses B0-31 in store 6, then the comparison unit 16 provides control unit 7 with its address and control unit 7 reads out the requested data group A0-31 to the data transmitting unit 11. At the same time, scanning device 17 changes the corresponding indicator C0-31 from 0 to 1 to show that access to that data group has recently been made. Immediately following the writing in of each new data group into store 6 the scanning device 21A starts searching for the next vacant location or the location which in an immediately preceding time period has least frequently been requested. To this end, device 21 searches for the next location still having its indicator C set at 0, said device resetting each such indicator C to 0 following its inspection. Having selected the next storage location to be used, the data group at present occupying that location is rewritten into main store 5 (with any amendments that may have been made) and the store 6 location is cleared. The rewriting of data into store 5 may be inhibited (if no amendment has occurred). Inhibit means may also be provided irrespective of whether amendment has occurred to prevent certain data groups from being transferred from store 6 to store 5 and also vice versa. The comparison of addresses in unit 16 may be done in parallel and the main store 5 may have provision for storing addresses in addition to data groups. Magnetic core storage is referred to as a store of relatively fast access time and magnetic tapes and discs as stores of relatively slow access time.
