In Multi-Processor System-on-Chip (MPSoC) architectures equipped with shared-memory, caches have significant impact on performance and energy consumption. Indeed, if the executed application depicts a high degree of reference locality, caches may reduce the amount of shared-memory accesses and data transfers on the interconnection network. Hence, execution time and energy consumption can be greatly optimized. However, caches in MPSoC architectures put forward the data coherency problem. In this context, most of the existing solutions are based either on data invalidation or data update protocols. These protocols do not consider the change in the application behavior. This paper presents a new hybrid cache-coherency protocol that is able to dynamically adapt its functioning mode according to the application needs. An original architecture which facilitates this protocol's implementation in Network-On-Chip based MPSoC architectures is also proposed. Performances, in terms of speed up factor and energy reduction gain of the proposed protocol, have been evaluated using a Cycle Accurate Bit Accurate (CABA) simulation platform. Experimental results in comparison with other existing solutions show that this protocol may give significant reductions in execution time and energy consumption can be achieved. |
