Towards High-Performance Bufferless NoCs with SCEPTER

In the many-core era, the network on-chip (NoC) is playing a larger role in meeting performance, area and power goals, as router buffers contribute greatly to NoC area and power usage. Proposals have advocated bufferless NoCs, however a performance wall has been reached such that high throughput performance has not been extracted. We present SCEPTER, a high-performance bufferless mesh NoC that …
