Due to scaling in recent trends in modern semiconductor industries, critical instance such as voltage spikes, temperature, interlink between IC circuits has been improvised under the design. The saturation throughput and average message delay are used as performance metrics to evaluate the throughput. We introduced the fuzzy logic based asynchronous NoC to attain the high throughput and diminish the delay between the inter logic circuits aim to select the less congested paths to produce load

... ance in the network especially under realistic traffic loads. Our Fuzzy logic based routing algorithm is an adaptive, low cost, and scalable. It outperforms against different adaptive routing algorithms in the average delay and saturation throughput for various traffic patterns. STDR can achieve up to 12%-32% average message delay lower than that of other routing algorithms. Moreover, the proposed scheme yields improvements in saturation throughput by up to 11%-82% compared with other adaptive routing algorithms.
