RiVAI Technologies has developed a microprocessor christened Lingyu CPU. The processor is also known as the first high-performance RISC-V server chip that China has entirely created on its own.
Large open-source language models like DeepSeek can be supported by the RISC-V server processor, which was created to support high-performance computing.
Less than one nanometer thick, Chinese scientists have created the most sophisticated two-dimensional (2D) semiconductor technology in the world.
Chinese researchers have developed a reduced instruction set computing architecture (RISC-V) microprocessor that can run standard 32-bit instructions on 5,900 MoS2 transistors and a full standard cell library based on 2D semiconductor technology.
There are 25 different kinds of logic units in the library. Researchers also co-optimized the 2D logic circuits’ design and process flow to match developments in silicon integrated circuits.
To suit a variety of computing needs, including machine learning, it may handle vector instruction sets and ultra-wide vector widths and provide more computational power.
According to reports, the final processor has 5,900 unique transistors and can implement the entire 32-bit RISC-V instruction set, which inevitably means it has complex hardware like the RISC-V instruction decoder. Nevertheless, some features are purposefully kept basic; for example, although it can add two 32-bit values, it does so by working on one bit at a time, which takes 32 clock cycles.
Due to the intrinsic drawbacks of traditional bulk semiconductors, the hunt for post-silicon semiconductors has intensified recently. However, these suffer from problems such a limited current on/off ratio dictated by semiconductor bandwidth, interfacial scattering-induced mobility degradation, and drain-induced barrier lowering.
According to reports, these difficulties have spurred the hunt for more sophisticated materials, and two-dimensional (2D) semiconductors that are atomic-layer thick have emerged as a possible remedy.
