The research team from Peking University has published significant research results in the prestigious international journal “Nature Electronics,” successfully developing a high-precision analog matrix computation chip based on resistive random-access memory (ReRAM). This breakthrough shines like a brilliant new star in technology, providing a new path for overcoming global computing power bottlenecks and attracting widespread attention in the tech community.
In today’s wave of digitalization, large-scale matrix operations play a core role in many critical areas such as signal processing in communication base stations and training of large AI models. However, traditional digital processors have long been constrained by the dual bottlenecks of high energy consumption and high latency when handling such operations, akin to a car struggling to move through mud, severely limiting the speed of technological development and application scope. The Peking University research team, leveraging exceptional innovation and strong research capabilities, has successfully enhanced the precision of analog computation to a 24-bit fixed-point level through dual innovations in new information devices and original circuit design. Their core technology cleverly combines low-precision matrix inversion with high-precision matrix-vector multiplication, employing an iterative refinement algorithm to achieve high-precision calculations, as if they have found a precise key to a technological problem.

Experimental data serves as the most compelling proof. When this chip processes a 128×128 matrix inversion, its computational throughput exceeds that of the current top GPUs by 1000 times, and its energy efficiency improves by over 100 times at the same precision. In real-time signal processing tests, it achieves the recovery effect of 32-bit digital computation with just 3 iterations. This series of astonishing data highlights the chip’s significant performance advantages, injecting a powerful impetus into the field of computing power. This scientific breakthrough holds substantial application value. In the context of signal processing for communication base stations, it can quickly and efficiently handle complex signal data, enhancing the quality and stability of communication, allowing for smoother information transmission. In the field of AI large model training, it can significantly reduce computational energy consumption and costs, accelerating model training and optimization, propelling artificial intelligence technology to new heights. It is believed that in the future, this high-precision analog matrix computation chip will shine in more fields, leading us into a more efficient and intelligent technological new era.
