  • Patent number: 9613389
    Abstract: A method for hiding texture latency in a multi-thread virtual pipeline (MVP) processor including the steps of: allowing the MVP processor to start running a main rendering program; segmenting registers of various MVP kernel instances in the MVP processor according to the length set, acquiring a plurality of register sets with the same length, binding the register sets to chipsets of the processor at the beginning of the running of the kernel instance; allowing a shader thread to give up a processing time slot occupied by the shader thread after sending a texture detail request, and setting a Program Counter (PC) value in the case of return; and returning texture detail and allowing the shader thread to restart running.
