TLB DEVICE SUPPORTING MULTIPLE DATA FLOWS AND UPDATE METHOD FOR TLB MODULE

摘要

A TLB device supporting multiple data streams and updating method for TLB module, wherein the device comprises: a control unit, corresponding to k data streams of the stream application to be processed, setting k TLB modules, each TLB module having two parts that are pages that correspond to each other and a page frame, completing a conversion from a logic address to a physical address by the mapping relationship between the page and page frame; wherein k is a natural number. The device and method of the present invention are directed to the characteristics of the stream application data stream itself, which may greatly reduce the occurrence of TLB miss in the process of conversion between logical address and physical address, thereby reducing the number of times of accessing the memory and greatly improving the performance of data access.
