Vector crossing multithread processing method and vector crossing multithread microprocessor

Abstract

The invention discloses a vector crossing multithread processing method and a vector crossing multithread microprocessor. The processing method comprises the following steps: using a multithread instruction-acquiring part to choose a vector thread from N vector threads for reading an instruction and storing the read instruction to a corresponding instruction buffer array of the vector thread; using a thread scheduling part to choose an instruction buffer array from N instruction buffer arrays and taking out an instruction from the instruction buffer array for the purpose of decoding; and sending a decoded instruction to a vector executing streamline or scalar executing streamline so as to execute. The method can be realized by using hardware structure by the vector crossing multithread microprocessor. The method and the microprocessor provided by the invention have the advantages that the vector processing technique and multithread technique are combined, the hardware structure is simple, the operation capability is strong, the compatibility and expansibility are excellent, and the like.

Description

technical field [0001] The invention relates to the field of computer microprocessors, in particular to a multi-thread microprocessor. Background technique [0002] With the rapid development of the computer field, the requirements for the processing power of the microprocessor are getting higher and higher, and there are two main ways to improve the computing power of the microprocessor: one is to improve the computing power of a single processor core; A processor core is integrated in a microprocessor chip, which is commonly referred to as multi-core technology. [0003] 1. To improve the computing power of the processor core, the traditional method mainly relies on increasing the frequency of the processor core and adopting superscalar technology with a larger instruction emission width. Due to constraints such as technology, power consumption and reliability, the processor frequency The improvement has encountered a bottleneck, and the instruction launch width is also d...

AI Technical Summary

Problems solved by technology

In recent years, with the development of multi-core technology, more and more processor cores are integrated on a single chip, but the computing power of the corresponding single processor core has not been significantly improved, and even decreased significantly in some designs.

Moreover, in order to give full play to the performance of multi-core processors, people pay more and more attention to the development of process-level and thread-level parallelism, while ignoring the research of instruction-level parallelism and data-level parallelism.
