Drive PX-series

The Nvidia Drive PX is a series of computers aimed at providing autonomous car and driver assistance functionality powered by deep learning. The platform was introduced at the Consumer Electronics Show (CES) in Las Vegas in January 2015.[1] An enhanced version, the Drive PX 2 was introduced at CES a year later, in January 2016.[2]

First generation

The first generation of Nvidia's autonomous chips was announced at CES 2015.[3] The line-up existed of two platforms: Drive CX for digital cockpits.

Drive CX

The Drive CX was based on a single Tegra X1 SoC (System on a Chip) and was marketed as a digital cockpit computer, providing a rich dashboard, navigation and multimedia experience. Early Nvidia press releases reported that the Drive CX board will be capable of carrying either a Tegra K1 or a Tegra X1.[4]

Drive PX

The first version of Drive PX is based on two Tegra X1 SoCs. It is targeted at (semi-)autonomous driving cars, and is being applied by Toyota.[5]

Second generation

The second generation was announced a year later at CES 2016.[6] This time only a new version of Drive PX was announced, but in multiple configurations.

Drive PX 2

The Nvidia Drive PX 2 is based on one or two Tegra X2 SoCs where each SoC contains 2 Denver cores, 4 ARM A57 cores and a GPU from the Pascal generation.[7] There are two real world board configurations:

There is further the proposal from Nvidia for fully autonomous driving by means of combining multiple items of the AutoChauffeur board variant and connecting these boards using e.g. UART, CAN, LIN, FlexRay, USB, 1 Gbit Ethernet or 10 Gbit Ethernet. For any derived custom PCB design the option of linking the Tegra X2 Processors via some PCIe bus bridge is further available, according to board block diagrams that can be found on the web.

All Tesla Motors vehicles manufactured from mid-October 2016 include a Drive PX 2, which will be used for neural net processing to enable Enhanced Autopilot and full self-driving functionality.[8] Other applications are Roborace.[9]

Xavier AI Car Supercomputer

Nvidia announced the Xavier AI Car Supercomputer at CES 2017.[10] Initial reports of the Xavier SoC suggested a single chip with similar processing power to the Drive PX 2 Autochauffeur system.[11] However, in 2017 the performance of the Xavier based system was later revised upward, to 50% greater than Drive PX 2 Autochauffeur system.[10]
