通过在NOC结构的路由节点中使用公共缓冲器而不是分布式缓冲器来减少分组延迟

Reduction in Packet Delay Through the use of Common Buffer over Distributed Buffer in the Routing Node of NOC Architecture

Nilesh A. Mohota, Sanjay L. Badjate

摘要:

根据延迟对路由节点进行性能评估是输入模块中缓冲区高效设计的特点。它的目的是研究和量化的行为的单包阵列设计的多包阵列设计。当在每个输入端口中使用公共缓冲器而不是单独的缓冲器时,提高了分组缓冲器阵列的利用效率。首先建立了Poissons时延模型来描述分组时延的差异。排队模型可分为(M/M/1)、(32/FIFO)等。到达率被假定为泊松分布,平均到达率为10 x 1000000。假设服务速率呈指数分布,平均服务速率为10.05 x 1000000。据观察,公共缓冲区的延迟比其分布式缓冲区提高了46%。随后在MATLAB上仿真Simulink模型以计算分组延迟的改善。已经观察到,通过使用公共缓冲器,延迟改善了大约40%。一个verilog RTL的公共和共享缓冲区已准备好,后来综合使用设计师的SYNOPPARY。在分布式缓冲区中,数据包的到达可以延迟2或4个时钟周期,这导致延迟在公共缓冲区中分别提高17%或34%

英文摘要:

Performance evaluation of the routing node in terms of latency is the characteristics of an efficient design of Buffer in input module. It is intended to study and quantify the behavior of the single packet array design in relation to the multiple packet array design. The utilization efficiency of the packet buffer array improves when a common buffer is used instead of individual buffers in each input port. First Poissons Queuing model was prepared to manifest the differences in packet delays. The queuing model can be classified as (M/M/1), (32/FIFO). Arrival rate has been assumed to be Poisson distributed with a mean arrival rate of 10 x 1000000. The service rate is assumed to be exponentially distributed with a mean service rate of 10.05 x 1000000. It has been observed that latency in Common Buffer improved by 46 percent over its distributed buffer. A Simulink model later simulated on MATLAB to calculate the improvement in packet delay. It has been observed that the delay improved by approximately 40 percent through the use of a common buffer. A verilog RTL for both common and shared buffer has been prepared and later synthesized using Design Compiler of SYNOPSYS. In distributed buffer, arrival of data packet could be delayed by 2 or 4 clock cycles which lead to latency improvement either by 17 percent or 34 percent in a common buffer
