HHSR:一种命令与数据分传片上网络原型

摘要

在前面工作的基础上,根据大规模、超大规模片上网络互连结构的性能特点,针对网络所传输信息的不同特性以及对传输的不同要求,提出了一种命令与数据分传的片上网络原型系统HHSR.该原型系统分别在两套具有不同拓扑结构的片上网络中传输命令和数据,选取速度较快且综合性能较好的单环分级互连网络用于命令包的传输,以满足其实时性的要求,选取速度稍慢但成本较低的六边形Mesh网格用于数据包的传输.实验结果表明,这种命令与数据分传的片上网络原型系统在牺牲一定的数据包传送时间和花费一定成本的基础上,保证和提高了命令与控制信息的传送速度,从而保证和提高了整个片上多处理器的性能.%Based on the previous research, a kind of novel network-on-chip which transfers commands and data separately was proposed,with regard to the different requirements for the commands transmission and the data transmission in chip-multiprocessors and the characteristics of different topologies in the large and very-large scale. A prototype to this novel network-on-chip named HHSR was presented. HHSR transfers commands and data in two networks-on-chip with different topology in the same chip-multiprocessor, which transfers commands in single hierarchical ring,a kind of network-on-chip with higher speed and higher general performance, to meet the needs for real-time to the commands transmission, and data in 2-D hexagon mesh grid,a kind of network-on-chip with lower speed but lower cost The prototype guarantees and improves the transmission speed of the commands so as to guarantee and improve the performance of the whole chip-multiprocessors with a little speed-down to the data transmission and a little more cost
