Abstract
1398204 Digital data storage INTERNATIONAL BUSINESS MACHINES CORP 10 Sept 1973 [16 Nov 1972] 42404/73 Addition to 1313444 Heading G4C [Also in Division H3] The data storage system of the parent Specification 1,313,444, in which address bits a and data bits d of pages of data are stored in shift registers having recirculation loops L1 and L2 respectively including and excluding the read/ write access position K, is modified in that one bit (e.g. the lowest order) of a requested page address is used to control the direction of shifting so as to reduce the access time. Recently accessed pages are maintained in positions for successive shifting into the access position K in preference to other pages, the arrangement described storing pages with even-numbered addresses at the right-hand end of the registers and those with odd-numbered addresses at the left-hand end. The address of a requested page is supplied over lines 118, the lowest order address bit determining the direction of shift signals produced by a shift control unit until a comparator ACU detects a match, whereupon the shift control unit is conditioned for shifting in the opposite direction to restore the pages to the order of most recent access leaving the last accessed page in position K. The number of shifts required to access the desired page is counted in a reversible counter 200 which controls the number of shifts which take place in the restore operation in conjunction with a latch 310 which is set by the lowest order address bit. Magnetic bubble shift registers are described for use in the system, the shift control unit supplying a reversible rotating magnetic field to effect shifting in the registers. The use of FET registers is also mentioned.
