Abstract

The invention relates to an SIMT condition branch processing device and method. The device comprises branch processing device hardware, an instruction and a programming model, wherein the branch processing device hardware is respectively connected with the instruction and the programming model, the instruction and the programming model are connected, and the branch processing device hardware is ahardware carrier executed by an external user code and has a relationship from the external user code; wherein the instruction provides a use interface of the device for an external user code and hasa relationship with the external user code; the programming model provides constraints and limitations of an instruction sequence during use for external user codes, and has a relationship to the external user codes. The invention provides a low-cost and easy-to-implement scheme for conditional branching of the SIMT processor, and is simultaneously suitable for a fine-grained SIMT multi-thread processor and a coarse-grained SIMT multi-thread processor.

Description

technical field [0001] The invention belongs to the technical field of processor and graphic processor design, and in particular relates to a SIMT conditional branch processing device and method. Background technique [0002] In a coarse-grained multi-threaded processor, when the current thread encounters a long-delay event, it uses processor resources by switching to other threads to cover up the pause caused by the long-delay event. However, the thread switching of coarse-grained multithreading only occurs when a long-delay event is encountered, and the switching frequency is low. Generally, the thread scene is saved by the operating system. Therefore, when the thread is switched, the preservation and loading of the thread scene requires a certain amount of overhead. During this period, the computing resources of the processor are idle. [0003] In the fine-grained multi-threaded processor, thread switching is also used to cover up the pause caused by long-delay events. U...
