Huami releases Huangshan 2S chip: dual-core RISC-V architecture, graphics acceleration performance improved by 67%

  Huami Technology held the Next Beat conference this afternoon, at which the self-developed new generation chip which should be used in wearable devices，Huangshan 2S was officially released.

  As soon as the press conference opened, Huami Technology founder, chairman and CEO Huang Wang reviewed the road of Huami's self-developed chip: In 15 years, it began to lay out the upstream and downstream chip industry, and in 18 years, it invested in the invention of RISC-V, the open source instruction set: SiFive. In September of the same year, Huami independently developed the first artificial intelligence chip Huangshan No. 1 in the global smart wearable field. In June 20, it updated the Huangshan No. 2 with superior performance and power consumption.

  Huangshan 2S is the first wearable artificial intelligence processor with dual-core RISC-V architecture. The super-powerful core computing performance can support high-load calculations such as graphics and UI operations. The large-core system also integrates FPU to support floating-point operations. Compared with Huangshan No. 2, the computing performance of Huangshan 2S is greatly improved, and the operating power consumption is greatly reduced.

  The Huangshan 2S chip integrates a 2.5D GPU, which can increase the graphics acceleration performance by 67% compared to Huangshan 2. Equipped with a convolutional neural network acceleration processing unit can quickly identify the type of disease. Taking atrial fibrillation as an example, its recognition speed is 26 times faster than pure software calculation. Huangshan 2S has been successfully taped out in March this year and will become one of the core chips of the third-generation Amazfit smartwatch.

  Huami Technology stated that the company has invested an average of 410 million yuan in research and development expenses in the past three years. Last year, it invested 538 million yuan, which is 2-3 times that of other emerging Internet companies and IoT smart hardware companies. The high R&D investment has produced more than 1,000 patents, nearly half of which are invention patents. There are nearly 100 core invention patent applications in the United States, and all patents have now been authorized up to 550.
