As technology is improving and the performance of a single core has reached its peak performance, Multicore Systems on Chip have emerged as the trend of System on Chip designs to meet the performance requirements of high throughput embedded applications. The communication infrastructure (interconnect) of such systems are as vital as its various other computational and storage units. A good design of the interconnect plays a significant role in improving the performance of the system. Bandwidth, area and power requirements of the system make the interconnect design a challenging task. At Intel, heterogeneous Multicore System on Chips are designed for imaging applications. The current system bus based interconnect used in these systems do not meet the performance, area and power requirements of future generation chips. Furthermore, it suffers from being fully connected. For this reason, the interconnect design is migrating to a ring based Network on Chip interconnect. This thesis implements a flexible framework to test and validate the ring interconnect (RI). Using this framework, one can analyze the response of the ring infrastructure for different topologies, reservation mechanisms and traffic scenarios and then configure the RI for a real world traffic scenario. We propose distinct RI configurations to meet the requirement of such a scenario. Furthermore, this framework will allow Intel to verify if the infrastructure fulfills the required performance of imaging applications in the pre-silicon stage.
