Samsung unveils the first 5G modem for cars, plus a chipset for in-vehicle infotainment
Cars are catching up with smartphones in terms of computing power and connectivity – thanks to Samsung’s new modem, future models will be able to connect to 5G networks and enjoy download speeds of up to 5.1 Gbps.
Exynos Auto T5123 is the first 5G modem designed specifically for car use, and it is already being mass-produced. Car parts have strict requirements for durability and longevity, so car manufacturers can not just use chips intended for smartphones.
This is actually more than just a modem. It has a pair of Cortex-A55 cores CPU cores and can provide satellite position data for navigation. By operating double duty, this chip reduces the total number of chips for the vehicle, which simplifies the design.
While the T5123 handles connectivity and positioning, the Exynos Auto V7 chipset (8 nm) can be the brainchild of mid-to-advanced vehicle infotainment setup. It can be configured with up to 32 GB LPDDR4x RAM (68.3 GB / s). The number crunches out of eight Cortex-A76 CPU cores clocked at 1.5 GHz (no small cores) and a Mali-G76 GPU with 11 cores.
The GPU is actually divided into two clusters – eight cores reproduce graphics for the central information display on the dashboard, while the remaining three cores operate the display in the instrument panel and an optional AR heads-up display. Separating the GPU cores into clusters ensures that what happens in one does not affect the other (reliability is the key).
The chipset actually supports up to four screens, so it can serve the passengers in the back seats as well. There are also three built-in sound processors so that the chipset can output more sound streams. Plus, there is an NPU for AI applications (because of course there is), it can talk, face and gesture recognition. This can be used for everything from voice commands to building a driver monitoring system.
There’s more, the V7 can also handle up to 12 cameras to provide features like surround view and parking assistance. The image processing system offers poor pixel correction, dynamic range compression, and geometric distortion correction.
Exynos Auto V7 has also entered mass production and will power next generation infotainment systems for vehicles. Among them is Volkswagen’s latest In-Car Application Server (ICAS) version 3.1, which is designed by LG Electronics’ Vehicle component Solutions division.
The third and final chip announced today is a power management IC designed specifically for the Exynos Auto V7 and V9. It received an ASIl-B certification earlier this year. The chip has built-in protection against various harmful conditions – overvoltage and undervoltage, short circuits, overcurrent and thermal interruption.
