Mi Band 4 likely to use Huami’s RISC-based Huangshan No.1 Chip

Xiaomi’s best selling Mi Band series is getting a new update tomorrow i.e. June 11. Before its official release, we have got some exciting news about the processor that powers the new Mi Band 4. Huami’s CEO, Wang Huang has just teased that the AI-powered Huangshang No.1 chip has been mass-produced. He’s likely talking about the Mi Band 4 since the official Mi Band page on Weibo has forwarded his post.

Huangshan No.1 was released late last year by Huami. The processor is said to be more efficient than ARM’s Cortex M4 based competitors. This is a really big move for Xiaomi since it would mean that the Chinese smartphone maker is trying its hands on an open-source RISC-V based processor instead of the more popular ARM alternative. The timing is also significant, since just a couple of days back, we reported that Qualcomm made a big investment in SiFive, the leading provider of RISC-V based processor IP. So, it looks like companies are increasingly looking for alternatives to ARM’s Cortex based chip designs.

The Huangshan No. 1 (MHS001) is the world’s first wearable processor that features an integrated AI-neural network. There are four core artificial intelligence engines — cardiac biometrics engine, ECG, ECG Pro, and Hearth Rhythm Abnormality Monitoring Engine.
