TELEFONAKTIEBOLAGET L M ERICSSON, S-126 25 STOCKHOLM, SWEDEN APPARATUS IN CONNECTION WITH A COMPUTER MEMORY of the disclosure: Apparatus in connection with a computer memory, enabling a step by step transportation of an empty memory field through an adjacent data field, while the computer is operative, by successive transfer of the information stored in the memory words of the adjacent data field from one side of the empty memory field to the other, the latter field thus dividing the data field into two field portions during the transportation. Incoming addresses, referring to a continnous area representing a data field being transferred, are converted 80 that the addresses instead refer to the two field portions. The continuous area is preferably identical with the transferred data field in one of its extreme positions, i.e. either the original position or the final position. By means of comparators the incoming addresses are compared with certain of the border addresses which delimit the field portions, thus determining whether the incoming address has to be modified or not. When modification is to be made the address is incremented by an amount corresponding to the size of the empty memory field. |
