Data read-write scheduler and reservation station used for vector operation

Abstract

The invention provides a data read-write scheduler and a reservation station used for vector operation. In the data read-write scheduler, a read instruction buffer module and a write-in instruction buffer module are arranged, the read instruction buffer module and the write-in instruction buffer module mutually detect conflict instructions, when conflict exists, execution of the instruction is paused, the instruction is re-executed when the time is ripe, and therefore writing after reading conflict and reading after writing conflict between instructions are solved, the fact that correct data is provided for a vector operation part is guaranteed, and the data read-write scheduler has good promotion and application values.

Description

Technical field [0001] The present invention relates to the field of computer technology, in particular to a data read-write scheduler and reservation station for vector operations. Background technique [0002] Vector operations, especially matrix operations, are widely used in machine learning, pattern recognition, image processing, graph computing and other fields. In particular, the deep learning algorithms developed in recent years have received increasing attention due to their high recognition accuracy and good parallelism. [0003] Vector read and write instructions will read and write multiple data at the same time within a single instruction. Multiple vector read and write instructions are often interdependent due to algorithms. On the one hand, vector read and write instructions may have their read addresses afterwards. There are overlapping vector write instructions, that is, read and write conflicts. On the other hand, there may be vector read instructions that overla...
