SLCAO: an effective system level communication architectures optimization methodology for system-on- chips

This paper proposes an effective system level communication architectures optimization (SLCAO) methodology to optimize the on-chip communication architectures (OCAs). SLCAO methodology divides the OCAs architecting into two steps: OCAs generation and OCAs optimization, and presents some valid bus mergence strategies to enhance the system performance and decrease the system cost from hierarchical buses through the analysis of the bus load. The methodology takes into account two categories of delay models, system delay model and PE-PE delay model, to evaluate the system performance and control the optimization process. The effectiveness of SLCAO methodology is illustrated by the 10-PEs example
