Lightelligence Pronounces Community-on-Chip Optical Processor – Top Efficiency Computing Information Research | insideHPC

Lightelligence hummingbird

Boston, June 28, 2023 Photonics computing corporate Lightelligence has offered Hummingbird, a network-on-chip (oNOC) optical processor designed for domain-specific AI workloads.

Lightelligence stated Hummingbird makes use of vertically stacked packaging applied sciences to combine a photonic chip and an digital chip right into a unmarried bundle that serves as a communications community for knowledge facilities and different high-performance programs. The primary public demonstration of the Hummingbird will probably be held at Sizzling Chips August 27-29 at Stanford College.

Photonics is the method to the vital downside of computing scaling, which has turn into pressing as conventional answers combat to stay tempo with the exponential enlargement in call for for computing energy spurred via breakthroughs in synthetic intelligence, notes Yichen Shen, CEO of Mild Intelligence. Hummingbird demonstrates how business can cope with scaling via incorporating photonics applied sciences into their subsequent era product.

Lightelligence is breaking the reminiscence wall with its proprietary photonics generation that would revolutionize the semiconductor business, provides Dylan Patel, leader analyst at SemiAnalysis.

Hummingbird is Lightelligence’s 2d product in its photonic pc portfolio. Its Photonic Mathematics Computing Engine (PACE) platform, launched in past due 2021, integrates photonics and electronics in a small shape issue via leveraging customized 3-d packaging and seamless co-design.

Hummingbird is the primary in a circle of relatives of goods the use of Lightelligence’s oNOC platform, designed to make stronger computing functionality via enabling leading edge interconnect topologies the use of silicon photonics. Its waveguides propagate alerts on the velocity of sunshine and use an all-to-all knowledge transmission community to each and every core on a domain-specific 64-core AI processor chip, giving the Hummingbird vital latency and tool aid in comparison to conventional virtual interconnect answers.

Compute scalability demanding situations impressed the introduction of an optical interconnect answer. Not like virtual networks, Hummingbird’s oNOC generation will increase density scaling via enabling interconnect topologies that may another way be infeasible.

In oNOC, energy and latency are just about unaffected via distance, making the generation ultimate for growing new and extra tough topologies that don’t depend on nearest neighbor conversation. oNOC topologies similar to Hummingbirds permit for upper usage of computing energy even in one digital IC configuration because of extra environment friendly conversation. With oNOC, mapping workloads to {hardware} turns into more uncomplicated and will provide you with extra freedom to choose the precise topology to your computing task.

In Hummingbird, Lightelligence has applied a low latency all-to-all optical broadcast community spanning 64 cores. With 64 transmitters and 512 receivers, Hummingbird supplies a framework for imposing a lot of dense optical community topologies.

Hummingbirds digital and photonic built-in circuits are co-packaged and built-in in a PCIe shape issue in a position for set up in business same old servers. Mixed with the Lightelligence Instrument Building Package (SDK), AI and device finding out workloads will also be optimized to take complete benefit of the oNOC. oNOC and Hummingbird IP may also be custom designed for different distinctive workloads and programs.

Long term generations of Hummingbirds will make use of reticle sewing to strengthen chiplet architectures to permit higher scalability, make stronger energy potency, and extra scale back bottlenecks.

Lightelligence stated it’s signing construction companions to pattern Hummingbird-based PCIe add-on playing cards along Lightelligence’s SDK in Q3 2023.
