Abstract :
A six-port four-lane 57GB/s router core features double-pumped crossbar channels and destination-aware channel drivers that dynamically configure based on the current flit destination. This enables 45% reduction in channel area, 23% overall chip area, and up to 3.8× reduction in peak channel power, depending on router traffic patterns. In a 150nm six-metal process, the 12.2mm2 core contains 1.9 million transistors and operates at 1GHz at 1.2 V.
