Abstract

In an era of multi-core and even many-core processors, with the increase of the number of cores integrated on a single-chip, how to organize these cores efficiently is becoming the key issue to make multi-processor systems optimal. The infrastructure of cluster-based multi-processor system-on-chip (MPSoC) is promising, and welcomed because of its hierarchy and scalability. However, how to configure the number of processing cores in each cluster has so far proved inconclusive. This paper shows the relationship between different processing core number configuration in each cluster and multi-processor system communication performance, and a C++-based cycle-accurate simulation model has established. The simulation model can be configured, and has fast simulation. When the total number of processing cores is fixed, changed the configuration of processing core numbers in each cluster, could get different system communication performance. Comparison of communication performance under different configurations to obtain the best, it may provide guidance to configure core numbers in the infrastructure of cluster-based MPSoC to gain a high communication performance.

基于集群的MPSoC基础架构通信性能研究

在多核甚至多核处理器时代，随着单芯片上集成的核心数量的增加，如何有效地组织这些核心成为多处理器系统优化的关键问题。基于集群的多处理器片上系统(MPSoC)基础结构因其层次性和可扩展性而备受欢迎。然而，到目前为止，如何配置每个集群中的处理核心数量尚无定论。本文给出了各集群中不同处理核数配置与多处理器系统通信性能之间的关系，并建立了基于c++的周期精确仿真模型。仿真模型可配置，仿真速度快。在处理核总数一定的情况下，改变每个集群中处理核数的配置，可以得到不同的系统通信性能。比较不同配置下的通信性能，以获得最佳的通信性能，可以指导基于集群的MPSoC在基础架构中配置核心数，以获得较高的通信性能。
