Abstract-With the increasing demand for efficient data processing, the latest consumer
electronics are powered by multicore processors. Many applications that run on these
devices expect minimum data access latency, where network-on-chip (NoC) plays a
crucial role. However, NoC is found to be responsible for 60%-75% of miss penalty. The
objective of this article is to present a revised NoC communication framework that can
possibly reduce the miss penalty. The proposed architecture orchestrates buffers of NoC
routers as a victim cache to store evicted cache blocks. Future references to such stored
blocks are replied from NoC routers, which significantly reduces miss penalty and
improves system performance. Minimizing miss penalty by maximizing NoC resource
utilization in these devices is a win-win situation.
& IN THE WORLD as it is today, data drives everything,
including most of the devices in consumer
electronics. The ever increasing data demand

efficient processing to make a quick decision. As
a result, all the devices that require processing
are realized by some form of a multicore processor.
For example, even the simplest of hand-held
devices in consumer electronics, like smartphones
are powered with at least a quad-core or
even an octa-core processor, and the count
