Chronos: An Abstract NoC-based Manycore with Preserved Temporal and Spatial Traffic Distribution

Abstract

The time spent to assess the application performance through clock-cycle simulators is a bottleneck of an NoC-based manycore design; thus, requiring higher abstraction levels at early design stages. However, high-level synchronization of processing and communication in such systems is a challenge. This work develops and validates Chronos, an untimed abstraction of an NoC-based manycore, built with Open Virtual Platform, that seeks precise traffic modeling in such a way to preserve the temporal and spatial distributions of the physical implementation. Results show the similarity of the temporal and spatial traffic distributions compared to a reference RTL-level platform.

Chronos-v: a many-core high-level model with support for management techniques

“…We adopt Open Virtual Platform (OVP) [33] to model and simulate the platform. The Chronos-V model preserves the temporal and spatial traffic distributions when compared to the physical implementation [34].…”
