To bring the benefits of CMT to larger workloads, these systems had to scale beyond a single socket. Because CMT requires massive memory bandwidth to achieve adequate throughput performance, the challenge was to develop a coherency link and fabric th

Time-of-flight synchronization is a new digital design methodology for optoelectronics that eliminates latches, allowing higher clock rates than alternative timing schemes. Synchronization is accomplished by precisely balancing connection delays. Cir

Time-of-flight synchronized optoelectronic circuits capitalize on the highly controllable delays of optical waveguides. Circuits have no latches; synchronization is achieved by adjustment of the lengths of waveguides that connect circuit elements. Cl
