The Photonic Arithmetic Computing Engine (PACE) is Lightelligence's groundbreaking integrated photonic computing platform. At its core is a 64x64 optical matrix multiplier, combining an advanced silicon photonic chip with a CMOS microelectronic chip, both meticulously flip-chip packaged into a single unit. With the incorporation of over 12,000 discrete photonic devices, the platform operates at a clock speed of 1GHz.
PACE is known for its optical multiply-accumulate (oMAC) capability, where input vectors are converted from digital into optical signals. These optical signals navigate through the matrix, producing output results that are converted back into digital form. This unique process significantly reduces latency and boosts energy efficiency compared to traditional electronic computation methods.
The platform's ability to efficiently process complex computational problems, such as the Ising problem, showcases its potential in bioinformatics, route planning, and material research & development. Lightelligence's PACE is also optimized for scalability, offering a robust solution for accelerating various algorithms used in modern computing tasks.
