Artilux Unveils Inception™

Artilux has made a groundbreaking announcement with the launch of Inception™, a new hybrid optoelectronic architecture that promises to change the landscape of AI computing. This innovative approach marks a significant departure from traditional digital electronics, enabling impressive enhancements in both power efficiency and area performance—achievements that conventional methods struggle to match.

As AI applications continue to expand rapidly across various platforms including cloud computing, edge devices, and personal devices, current digital processors are hitting their limits. These limitations are primarily seen in factors such as energy consumption, chip dimensions, data transfer inefficiencies, and thermal management challenges. Inception™ steps in to tackle these issues by fundamentally rethinking how computations are performed.

The Core Technology

At the heart of Inception™ lies a distinct optoelectronics-enabled hybrid systolic array architecture that is not only compatible with existing CPU, GPU, TPU, and LPU architectures but also excels at executing large-scale general matrix-matrix multiplication (GEMM), a foundational workload in contemporary AI tasks. Notably, Inception™ offers solutions without data skew and with minimal propagation delays, ensuring rapid processing capabilities.

This hybrid design blends analog and digital elements, facilitating substantial parallel computations through a dense 2D array of optoelectronic neurons (OENs). Each OEN integrates a light emitter (like a GaN micro-LED), a photodetector (such as a GeSi pixel), and local in-pixel memory. The inputs and weights necessary for perform multiply-accumulate (MAC) operations are represented through modulation of light signals, followed by local charge storage and configurable activation processes. This smart architecture eliminates the traditional need for Arithmetic Logic Units (ALUs) typically used for GEMM, which are predominantly constructed from pipelined digital electronics.

Moreover, this innovative architecture significantly reduces memory bandwidth by enabling extensive reuse of inputs and weights fetched from external memory during the calculations, thereby lowering energy needs associated with data movement. This capability is especially vital for transformer-based AI tasks that require swift dynamic weight updates.

Inception™ can be fabricated using mature CMOS processing technologies, which align seamlessly with current semiconductor manufacturing techniques. The design leverages the exceptional power efficiency per area characteristic of the optoelectronic architecture, ensuring that no active cooling systems are required. This factor not only reduces the complexity of system deployment but also minimizes associated costs.
