A Methodology for the Design of High-Performance Communication Architectures for System-On-Chips Using Communication Architecture Tuners

Technology Application

This invention should find ready application in the realization of high performance system-on-chip communication architectures.

Detailed Technology Description

This invention is a general methodology for the design of custom system-on-chip communication architectures, which are flexible and capable of adapting to the varying communications needs of system components. The disclosed technique can be used to optimize any underlying communication-architecture topology by rendering it capable of adapting to the changing communication needs of the components connected to it. For example, more critical data may be handled differently, leading to lower communication latencies. This results in significant improvement in quality of service (QoS) metrics, including the overall system performance, observed communication bandwidth and bus utilization, and the system's ability to meet critical deadlines. The present technique is based on the addition of a layer of circuitry, called the communication architecture tuner (CAT), to each component. The CAT monitors and analyzes the internal state of, and communication transactions generated by, a system component and "predicts" the relative importance of communication transactions in terms of their impact of different system-level performance metrics. The results of the analysis are used by the CAT to configure the parameters of the underlying communication architecture to best suit the component's changing communication needs.
