On-chip network band width resource scheduling method for ensuring service quality

Abstract

Disclosed is a network-on-chip resource scheduling method which ensures the quality of service and relates to a connection-orientated resource scheduling method which bases on the network-on-chip and ensures the quality of service. The resource scheduling method aims to solve the disadvantages of conflict transmission, low utilization ratio of network resource and affecting the BE service quality found between different GS connections which share the same physical link of the network-on-chip which provides the ensured quality of service in the prior art. The resource scheduling is realized through the steps as follows: step1, the priority of the GS virtual connection is created and set; step2, the GS virtual connection is synchronized through the priority counter in a router; step3, the initial priority of the BE path is set; step4, the DSD is scheduled to output; step5, the GS virtual connection is cancelled. The resource scheduling method solves the problem of conflict transmission between different GS connections which share the same physical link, realizes various bandwidth hard ensured services for IP and solves the disadvantages of low utilization ratio of network resource and affecting the BE service quality found in the GS service ensuring method which adopts the oriented connection.

Description

technical field [0001] The invention relates to a network resource scheduling method, in particular to a network-on-chip connection-oriented resource scheduling method capable of guaranteeing service quality. Background technique [0002] Currently, the network-on-chip provides quality-of-guaranteed services mainly through a connectionless-oriented data packet prioritization method or a connection-oriented GS (Guarantee-Service) virtual connection method. Among them, the connectionless data packet prioritization method can only provide statistically significant service quality assurance. When there are many high-priority data packets, the guaranteed service quality will decline. In many multimedia applications, real-time data Stream transmission needs guaranteed quality transmission guaranteed by hard QoS (Quality of Service) indicators such as bandwidth, delay, and delay jitter. The priority-based method cannot provide such services; although the connection-oriented GS virt...
