Title:
POINTER TRANSFER DEVICE, POINTER TRANSFER METHOD, AND MEMORY CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/170815
Kind Code:
A1
Abstract:
A read-side read pointer synchronization unit (109) synchronizes a read pointer (208) with a write clock (WCLK) and takes in the result, said read pointer (208) having been generated on the side of a memory read circuit (201) which synchronizes with a read clock (RCLK). A write-side agreement detection unit (113) performs an agreement comparison between the value of a write-side read pointer (110) that is calculated by a write-side read pointer calculation unit (112), and the value of a read-side read pointer (111) that was taken in by the read-side read pointer synchronization unit (109). As long as the write-side agreement detection unit (113) detects non-agreement, the write-side read pointer calculation unit (112) changes the write-side read pointer (110) by one each cycle of the write clock (WCLK).
