A balanced pipeline tuned for throughput — the compute element that coordinates clusters through the fabric.
Features

Built for coordination at scale.

Throughput

Wide superscalar

10-wide and 16-wide out-of-order configurations for heavy coordination workloads.

Coherence

Many-core coherent

Cache-coherent across the cluster, connected through our network-on-chip.

Proven

Linux on FPGA

Not a spec — a core you can watch boot in our architectural visualizer.
