Method, device and processor for generating data by multidimensional array sliding

Abstract

An embodiment of the invention provides a method and a device for generating data through multi-dimensional array sliding as well as a processor. The method for generating the data through the multi-dimensional array sliding comprises steps as follows: a first element and a second element with the same length are acquired through execution of a multi-dimensional array sliding operation instruction; a first N-dimensional array and a second N-dimensional array are formed by the first element and the second element respectively according to the same default rule; the first array and the second array are spliced in a direction of the first dimension; starting from an original point of the first dimension, an N-dimensional sliding window slides for a movement amount of bytes along the first dimension on the spliced N-dimensional array; all array elements in the N-dimensional sliding window after sliding are acquired to constitute a target element. According to the embodiment of the invention, the target element meeting a required data mode is extracted from the two source elements efficiently and conveniently, and the efficiency of the processor is improved, so that the processor is more efficient when used for solving specific problems in the related scientific computation field or the digital signal processing field.

Description

Technical field [0001] The embodiments of the present invention relate to computer technology, and in particular to a method, device and processor for generating data by sliding a multi-dimensional array. Background technique [0002] Nowadays, there are more and more applications that need to implement efficient data calculations, so more efficient Single Instruction stream Multiple Data streams (SIMD) processors are needed to execute more efficient SIMD instructions, so how Generating the data format required by the corresponding SIMD instruction according to the specific application has become a very critical link in the effective implementation of SIMD processing. [0003] However, the existing data format formation through asymmetric memory access, sliding operations, etc. requires multiple memory access operations or sliding operations, which will cause a long processing time problem and reduce the efficiency of the processor. Summary of the invention [0004] The embodiments...
