Rockchip RK3588M automotive-grade AI SoC supports up to 16 camera inputs

Rockchip RK3588M

Rockchip RK3588M is an automotive-grade variant of the Rockchip RK3588 octa-core Cortex-A76/A55 SoC that supports at least 6 Full HD displays and 16 camera inputs and can simultaneously run the car dashboard, in-vehicle infotainment, a digital rearview mirror, headrest monitors, ADAS system, and more.

The frequency of the Cortex-A76 cores is limited to 2.1 GHz, and the Cortex-A55 cores to 1.7 GHz, against 2.4 and 1.8 GHz for RK3588, probably to operate in a larger temperature range required by the automotive market. I could not find any RK3588M datasheet yet, but we can find more details through the Firefly AIO-3588MQ automotive mainboard built around the RK3588M processor.

RK3588M SBC specifications

The company offers support for Android 12.0, Ubuntu Desktop and Server, Debian 11, and buildroot RTLinux for the board//system-on-module. Firefly also mentions Kernel-based Virtual Machine
(KVM) and Docker container support, as it will be necessary to support critical (e.g. dashboard) and non-critical (e.g. infotainment) parts of the software with isolated and likely different operating systems. Technical documentation can be found in the Wiki to get started with Android, Linux, and RTLinux.

The first time I found out about the RK3588M was in a demo last February at the RKDC (Rockchip Developer Conference) showing a system driving four independent displays and two gamepads.

Firefly is selling samples of the AIO-3588MQ automotive-grade AI mainboard on its store for $539 with 8GB RAM and 32GB flash, and $759 in 16GB/128GB configuration. Additional information may also be found on the product page.
