Here's one way past Moore's law: Chips that mix photonics and electronics
As Intel, TSMC, and Samsung race to prove that Moore's law is still relevant with faster and more efficient chips, researchers in China have pointed to a growing body of research revealing one way silicon slingers can achieve higher levels of performance: matrix math accelerators that integrate electronic circuits and photonics.in the peer-reviewed Advanced Photonics journal. The review was conducted by two academics at the Chinese Academy of Sciences and Peking University in China.
The eggheads, Pengfei Xu and Zhiping Zhou, argue that optoelectronic chips may not make sense for all types of general-purpose computations. But when it comes to performing matrix operations – which are crucial for high-performance workloads such as AI, simulations, and graphics rendering – optoelectronic chips"have the potential to surpass the computation performance" of traditional electronic processors"in terms of energy efficiency, computational power, latency, and maintainability," according to the duo.
"We believe that silicon-based optoelectronics is a promising and comprehensive platform for general-purpose matrix computation in the post-Moore's law era," Xu and Zhou wrote.
