## Key points

- Toyota and AISIN have developed an AI chip with integrated memory.
- Its kernel startup is reported to be 38 times faster.
- AISIN has not announced a production timetable.

## Summary

Toyota and automotive supplier AISIN have developed an AI system-on-chip that stores model weights and its operating system in built-in memory. They say keeping this data on the chip can reduce delays caused by accessing external memory, potentially improving AI tasks such as image recognition in cars and robots.

The chip uses a 16nm FinFET process, a dual-core Arm Cortex-A53 CPU, an Arm Mali-G31 GPU and STT-MRAM. AISIN and Tohoku University report that it starts its operating system kernel in 65.7 milliseconds, 38 times faster than with external memory, and can run Tiny YOLOv3; a hybrid multiplication design reduced the model’s weight data by 53%, from 17.7MB to 9.36MB, while maintaining 16-bit precision. AISIN has not said when the chip might enter production, while Nvidia and Qualcomm are also targeting automotive AI.
