Double core interconnection! Vivo video chip V2 and Tianji 9200 are interconnected and synchronized within 1/100 second

I really have to marvel at the development speed of the mobile phone industry. Vivo has become the focus of everyone's attention recently, especially after the release of the new self-developed chip V2 and the new system. Tianji 9200 will also be launched in Vivo worldwide. The dual core interconnection is one of the highlights. According to the latest news, the video chip V2 and Tianji 9200 will be interconnected and synchronized in 1/100 second.

Since 2021, vivo has launched two generations of self-developed chips, V1 and V1+. This self-developed chip V2 uses a new iterative AI-ISP architecture, which brings about comprehensive improvement in compatibility and functionality. On chip memory units, AI computing units, and image processing units have been significantly upgraded.

Put forward FIT dual core interconnection technology, establish a new high-speed communication mechanism between self-developed chip V2 and Tianji 9200 flagship platform, enable two chips with completely different architectures and instruction sets to complete dual core interconnection synchronization in 1/100 second, and achieve optimized coordination and high-speed collaboration of data and computing.

It is reported that thanks to the near memory DLA (vivo self-developed AI deep learning accelerator) module and the large capacity dedicated on-chip SRAM (high-speed and low-power cache unit), the self-developed chip V2 rematched the computing power capacity, computing power density and data density, greatly improving the capacity and computing speed of the on-chip cache. Compared with the DDR external memory design commonly used by NPU, the SRAM data throughput power consumption theory can be reduced by 99.2% at most, and the energy efficiency ratio can be improved by 200% compared with traditional NPU.

The structure design of FIT dual core interconnection and near memory DLA enables the AI-ISP architecture of self-developed chip V2 to be established, and complements the ISP algorithm and computing power with the platform chip NPU to achieve the ultimate image processing effect and energy efficiency ratio.

Two cores held by vivo not long ago × The video technology communication meeting really brightened many small partners' eyes. Many users did not pay attention to domestic mobile phones before, and did not expect that the development has become so rapid now. So you can look forward to the upcoming vivo X90 series.
