Amlogic V901D – A quad-core Cortex-A55 processor for in-vehicle infotainment

Amlogic has decided to enter the automotive market with the Amlogic V901D quad-core Cortex-A55 processor designed for in-vehicle infotainment (IVI) applications such as car dashboards, multi-camera dashcam systems, automotive multimedia players, and so on.

Also equipped with an Arm Mali-G31 MP2, a 1 TOPS NPU, support for 4K AV1 video decoding, and a 12nm manufacturing processor, Amlogic V901D may look like a rebranded Amlogic S905X4 at first glance, but as we’ll see below, it includes some features specific to the automotive infotainment market.

There’s no HDMI output at all since it’s not needed for this type of product, but Amlogic V901D supports multiple LCD display interfaces, comes with three HDMI 2.1 and two CVBS inputs probably for camera inputs, as well as AVB (Audio Video Bridge) support, and automotive AEC-Q100 grade 3 certifications.

The product page on Amlogic website has limited information, and at this point in time, I could not find any third-party resources or hardware based on Amlogic’s automotive processor.

Thanks to theguyuk for the tip.
