Mobileye and STMicroelectronics are co-developing the next (5th) generation of Mobileye's SoC, the EyeQ5, to act as the central computer performing sensor fusion for Fully Autonomous Driving (FAD) vehicles starting in 2020.

To meet power consumption and performance targets, the EyeQ5 will be designed in advanced 10nm or below FinFET technology node and will feature eight multithreaded CPU cores coupled with eighteen cores of Mobileye's next-generation and innovative vision processors. Taken together, these enhancements will increase performance 8x times over the current 4th generation EyeQ4, stated the company. The EyeQ5 will produce more than 12 Tera operations per second, while keeping power consumption below 5W, to maintain passive cooling at extraordinary performance. Engineering samples of EyeQ5 are expected to be available by 1H18.

The EyeQ5 continues Mobileye's long-standing cooperation with STMicroelectronics. Leveraging its substantial experience in automotive-grade designs, ST will support modern physical implementation, specific memory and high-speed interfaces, and system-in-package design to ensure the EyeQ5 meets the full qualification process aligned with the highest automotive standards. ST will also contribute to the overall safety- and security-related architecture of the product.

EyeQ5's proprietary accelerator cores are optimised for a variety of computer-vision, signal-processing, and machine-learning tasks, including deep neural networks. EyeQ5 features heterogeneous, fully programmable accelerators, with each of the four accelerator types in the chip optimised for its own family of algorithms. This diversity of accelerator architectures enables applications to save both computational time and energy by using the most suitable core for every task. This optimized assignment ensures the EyeQ5 provides "super-computer" capabilities within a low-power envelope to enable price-efficient passive cooling. Mobileye's investment in several programmable domain-specific accelerator families is enabled by its focus on the ADAS and autonomous driving markets.

Autonomous driving requires an unprecedented level of focus on functional safety. EyeQ5 is designed for systems that meet the highest grade of safety in automotive applications (ASIL B(D), according to the ISO 26262 standard).
