Description

technical field

[0001] The invention belongs to the field of computer and digital communication, and relates to a multi-core processor. All main processors and slave processors in the multi-core processor are ultra-long instruction word processors. technical background

[0002] The rapid development of digital communication, especially wireless communication, puts forward higher and higher requirements for the ability of digital signal processing. The method of increasing the digital signal processing capability by increasing the main frequency is limited by chip power consumption, heat dissipation and manufacturing process, and the expansion capability is limited. Very long instruction word (VLIW) and multi-core processor structure can well expand the ability of digital signal processor.

[0003] We know that a parallel computer or an ultra-long computer uses a network to connect some general-purpose processors or computers to provide powerful processor capabilities. The a...
