  • Memory access control circuit, prefetch circuit, memory device and information processing system
    Patent number: 9223704
    Abstract: Disclosed herein is a memory access control circuit including: a determination section adapted to determine whether a target requested by a first wraparound memory access request from a processor is stored in a prefetch buffer; a request generation section adapted to generate a second wraparound memory access request including the target if it is determined that the target is not stored in the prefetch buffer; and an address conversion section adapted to convert the start address of the first wraparound memory access request according to predetermined rules for use as a start address of the second wraparound memory access request.
    Type: Grant
    Filed: December 16, 2011
    Date of Patent: December 29, 2015
    Assignee: Sony Corporation
    Inventor: Yoshitaka Kimori

  • MEMORY-ACCESS CONTROL CIRCUIT, PREFETCH CIRCUIT, MEMORY APPARATUS AND INFORMATION PROCESSING SYSTEM
    Publication number: 20120185651
    Abstract: Disclosed herein is a memory-access control circuit including: a prefetch-size-changing-command detection section configured to detect a command to change a prefetch size of data transferred from a memory to a prefetch buffer; a transfer-state monitoring section configured to monitor a state of transferring data between the memory and the prefetch buffer; and a prefetch-size changing section configured to immediately change the prefetch size in the prefetch buffer when the command to change the prefetch size is detected and no state of transferring data between the memory and the prefetch buffer is being monitored and to change the prefetch size in the prefetch buffer after completion of the state of transferring data between the memory and the prefetch buffer when the command to change the prefetch size is detected and the state of transferring data between the memory and the prefetch buffer is being monitored.
