Abstract
PURPOSE: To make it possible to convert a sufficiently-large logical address into a physical address and also to enable high speed retrieval by controlling a conversion table in the format of multiple page indexes.
CONSTITUTION: An information processing system consists of processor 1, memory 2 stored with a multiple page tree maintaining a conversion table of logical addresses and physical addresses, and retrieval unit 3. Then, processor 1 sends logical addresses to be converted, e.g., three blocks B1, B2 and B3 to selector circuit 5 by way of register 4. Circuit 5 sends blocks B1 and B2 to associative memory 6 and B3 to adder 7. Memory 6 checks whether sent blocks exist or not and when so, corresponding physical addresses are added by adder 7 to store the sum in register 9. When not, a command is sent to selector circuit 5 to repeat selecting operation. Thus, a great quantity of addresses can be converted and high-speed retrieval can be attained.
