Data-intensive application-oriented network-on-chip approximate communication system

Abstract

The invention discloses a data-intensive application-oriented network-on-chip approximate communication system, and belongs to the technical field of network-on-chip. In order to solve the problems that in the prior art, network-on-chip for a data-intensive application is prone to congestion, time delay and the like, an approximate communication data transmission mode is adopted; a global controller is arranged in the network-on-chip; a network congestion condition monitoring unit is arranged in a router; and a data compression and decompression unit and a data screening unit are arranged in a port where the router is connected with a processing core. According to the invention, communication congestion conditions of network-on-chip can be effectively improved through supervision of network congestion conditions and a dynamic data approximation scheme, the communication delay of a data-intensive application is reduced, and the system has good use values and wide application prospects.

Description

technical field [0001] The present invention relates to the field of Network on chip (Network on chip, NoC) technology, and more specifically, relates to a network on chip approximate communication system oriented to data-intensive applications. Background technique [0002] With the continuous reduction of semiconductor process size, the industry has entered the "dark silicon" era, and the performance of a single processing core is gradually approaching the limit. Multi-core has become a hot spot in the research of the chip industry and the main development direction in the future. Compared with the bus structure, the multi-core communication architecture connected through the network on chip has the advantages of high bandwidth, good scalability, and low delay. The network on chip (Network on Chip, NoC) has become a paradigm structure for multi-core interconnection. , but it also means spending more time on data communication. [0003] Some current large multi-core chips ...
