Abstract

The embodiment of the invention relates to a method and an electronic device for loading data in a single-instruction multi-thread computing system. In the method, a plurality of predicates for a plurality of threads are determined based on a received single load instruction, each predicate indicating whether an address specified in a respective thread is valid, the address being used to access data in a memory; determining at least one execution thread in the plurality of threads based on the determined plurality of predicates; for each execution thread in the at least one execution thread, determining target data; and writing a set of target data for each of the at least one execution thread into a register file of each of the plurality of threads. In this manner, corresponding target data may be determined for each execution thread based on a single load instruction and a set of target data is written to each target thread. In this way, the efficiency of data exchange between the register and the memory can be improved.

Description

technical field [0001] Embodiments of the present disclosure relate generally to the field of electronics, and more particularly to a method and apparatus for loading data in a single instruction multithreading computing system. Background technique [0002] For a conventional single-instruction-multithreading computing system, each thread has its own register file (that is, an array of registers, also called a register file), and each thread can perform thread-level data exchange between its registers and memory. [0003] Currently, a typical load-store architecture is usually used to exchange data between registers and memories. For example, a load instruction may be utilized to read data from memory and store data into registers. However, conventional load instructions lack optimization for data exchange between multiple threads. Therefore, there is a need for a scheme for efficiently loading data for multiple threads in a single instruction multithreading computing sys...
