一种提高无缓存片上网络性能的方法
A Method of Raising Bufferless Network-on-Chip Performance
摘要
Abstract
In low load, bufferless Network-on-Chip (NoC) routing performance is better than buffered routing, and has the advantage of low-power dissipation and low latency. But in the condition of high load due to increased competition and the emergence of deflection decrease bufferless NoC routing causes more time-delay and energy consumption. Based on congestion control, a new way is proposed to reduce packet deflection on bufferless NoC in high load condition. The competition frequency of each output link of the router in the congestion register is recorded. When competition occurs on one output port, a count is increased in the corresponding register. According to the priority policies,while winning the route calculation flits through the effective output port, the other flits are deflected to an inactive output port of low congestion degree. This method, based on improvement of the priority control algorithm, can effectively reduce the number of flits deflection when the congestion occurs. Through the simulation, this method can effectively reduce the deflection and average delay of a flit in high load condition.关键词
