Abstract

This paper introduces flexible radio techniques inside integrated circuits in order to tackle the interconnect issue for many-core chips. We propose to take benefits from OFDMA for a RF-interconnect associated to a carrier allocation policy and adaptive modulation. A 20 GHz bandwidth is shared between 32 tile sets made of 32 tiles of 4 cores each, for a 4096 cores chip. We adopt a cognitive radio approach in order to dynamically share 1024 carriers, which avoids inter-cluster communication contention and decreases latency compared to conventional static approaches.
