Tim Yates, Senior Director of Product Management at Qualcomm, also attended the conference to interpret the AI features supported by Qualcomm Snapdragon 670. He said that the performance of the Snapdragon 670 is 1.8 times higher than that of the Snapdragon 660. At the same time, because of the processing of neural networks and fingerprint data, the DSP can significantly increase the processing speed compared with the CPU, resulting in a seamless and secure fingerprint unlocking experience. Also, Tim Yates said that the Hexagon DSP and trusted execution environment together deliver up to 3x faster speeds than using a trusted execution environment alone.

It can be simply taken as the first technical cooperation between Qualcomm and VIVO in terms of the screen fingerprint technology.

At the communication meeting, VIVO said that the ‘screen fingerprint DSP acceleration technology’ enabled the X23’s screen fingerprint to achieve a 30% significant increase in the unlocking speed. For the VIVO X23, this technology will be pushed through an update in October.
