AI Technical Summary

Problems solved by technology

Collisions in each loop are avoided, but additional data preprocessing is required due to data discontinuity
And this strategy assumes that the data must be able to be completely placed in the target memory, which is not conducive to subtask cutting

Abstract

The invention provides a data storage method of multi-bank memory, which includes: acquiring the current memory bank of each operation data. Through the greedy algorithm, when the least conflict and the least filling elements are obtained, the corresponding set transformation vector is used as the current transformation vector. Generates the current bank number for each current bank from the current transform vector. Get the corresponding internal offset address. Store the operation data in multiple storage banks according to the current memory bank number and internal offset address. The purpose of the present invention is to provide a data storage method for multi-bank memory, which disperses elements in different memory banks in an appropriate way through linear conversion, and divides applications into multiple small memory banks through subtask cutting. tasks, greatly reducing the application's demand for memory resources. At the same time, the invention also provides a data reading method of multi-bank memory and a data storage system of multi-bank memory.

Description

technical field [0001] The invention relates to the field of data storage and memory management. The invention specifically relates to a data storage method and system of multi-bank memory. Background technique [0002] As a promising option for domain-specific accelerators, coarse-grained reconfigurable architectures (hereinafter referred to as CGRAs) have attracted increasing attention due to their energy efficiency approaching that of ASICs and high software programmability. CGRA usually consists of a main controller (usually a CPU), a PE array, a main memory and a local memory (usually a multi-bank memory structure), such as figure 1 shown ( figure 1 Central host controller context memory instruction memory datamemory data memory PEA shared memory (SM) local data memory Parallel-access databus parallel access data bus PEA Global Regfile global register file output register output register local regfile local register file context buffer instruction cache Multi -bank P...
