Communication Bandwidth Adaptable Network Design of Complex Application Specific SoC

The communication interconnects among the cores of the futuristic SoC is a vital challenge. NoC is being proposed as the appropriate solution for addressing these communication challenges of complex SoCs. To address design complexity and reuse, NoC systems are typically desired to be built from predesigned and pre-verified homogenous or heterogeneous building blocks such as programmable RISC cores, DSPs, memory blocks. However most application specific SoC are special-purpose and are tailored to the domain-specific requirements of the desired application, which communicate in a very specific, mostly irregular way. In this work, a methodology for the design of communication centric customized irregular network infrastructure of SoC is proposed. The proposed methodology exploits a priori knowledge of the application’s communication attributes to generate an optimized network and associated routing tables to enable sufficient number of deadlock free paths for enhanced communication traffic and energy distribution across the network infrastructure of the SoC. In the proposed methodology the network is generated according to the requisite deadlock free paths having appropriate distribution of communication traffic.
