Design constraints of a hypertransport-compatible network-on-chip

Hypertransport (HT) is an emerging system integration communication technology. There is a need for a network on chip (NOC) technology compatible with this cutting-edge system technology. This paper reveals design constraints involved in implementing an HT-compatible NOC. In order to provide a simple and HT-compatible solution, we propose an architecture called hypertransport super lite (HTSL). The new architecture allows a reduction of more than 14 times in required buffer space, while keeping the functionality unaffected. Moreover, exploiting the advantages of on-chip architecture leverages the processing complexity of each node in the architecture.
