Non-Binary AI Chip
China has made leap in artificial intelligence with the deployment of non-binary AI chips. This advancement comes from Professor Li Hongge’s team at Beihang University. They have developed a novel computing approach called Hybrid Stochastic Number (HSN) computing. This innovation aims to address critical limitations in conventional computing.
About Hybrid Stochastic Number Computing
Hybrid Stochastic Number computing merges traditional binary logic with probabilistic logic. Binary systems operate on precise calculations using 1s and 0s, which are energy-intensive. In contrast, stochastic computing uses voltage signal frequencies to represent values, resulting in lower power consumption but often slower performance. The HSN system combines these approaches to achieve a balance of energy efficiency and computational reliability.
Addressing Key Limitations in Conventional Chips
Two major limitations challenge conventional chips – the power wall and the architecture wall. The power wall refers to the high energy demands of binary systems, making scalability difficult. The architecture wall marks the integration issues of non-silicon chips with existing CMOS infrastructure. HSN computing provides a solution by reducing energy consumption while maintaining performance.
Applications of Non-Binary AI Chips
The non-binary AI chip has been implemented across various sectors. In touch display systems, it enhances user interaction by filtering noise and accurately detecting weak signals. In medical and industrial displays, it enables rapid, low-power data processing for precise readings. In aviation, the chip ensures steady navigation and fault tolerance, crucial for aerospace operations. Its in-memory computing capability reduces energy-intensive data transfer, addressing bottleneck in traditional systems.
Overcoming Technological Restrictions
Despite facing US export restrictions on advanced semiconductor technology, Li’s team successfully built the chip using 110nm and 28nm manufacturing processes from Semiconductor Manufacturing International Corporation (SMIC). This approach allows China to innovate within its existing technological capabilities while bypassing high-end semiconductor limitations.
Future Developments in Chip Technology
Looking ahead, the team is working on a custom instruction set architecture (ISA) tailored for hybrid probabilistic computing. This will enable the chip to support advanced applications such as AI model acceleration, speech and image recognition, and neural networks. This technological pathway could allow China to achieve self-reliance in semiconductors, encouraging innovation independent of foreign technologies.
Implications for Global Technology
China’s approach to redefining computing logic could reshape global perspectives on chip development. By focusing on architectural innovation rather than merely increasing transistor counts, this strategy may lead to new methodologies in computing. This could influence how future chips are designed and utilised worldwide.
