Chip makers advancing in-car entertainment
- 04 October, 2013 13:23
Chip makers like Broadcom and Renesas Electronics are ramping up in-car entertainment with faster processors and networks for wireless HD movies and navigation, aiming to keep drivers informed and passengers entertained.
With PC sales slipping and the mobile device market proving highly competitive, chip makers are looking for greener pastures in other sectors like in-car entertainment and information.
From Renesas comes the R-Car M2 automotive SoC (System-on-a-Chip), which has enough power to handle simultaneous high-definition navigation, video and voice-controlled browsing.
The SoC is meant for use in mid-range systems. It features two ARM Cortex A-15 cores running at up to 1.5GHz and Renesas' own SH-4A processor plus the PowerVR SGX544MP2 from Imagination Technologies for 3D graphics. This combination helps the M2 exceed the previous R-Car H1 with more than three times the CPU capacity and approximately six times better graphics performance.
Car makers that want to put a more advanced entertainment system in their upcoming models should go for the eight core R-Car H2 SoC, which was announced earlier this year. It is based on ARM's big.LITTLE architecture, and uses four Cortex-A15 cores and another four Cortex-A7 cores.
The H2 will be able to handle four streams of 1080p video, including Blu-Ray at 60 frames per second, according to Renesas. Mass production is scheduled for the middle of next year, while the M2 won't arrive in larger volumes until June 2015.
Broadcom on the other hand is seeking to drive better networking on the road. The company's latest line of wireless chipsets for in-car connectivity uses the fast 802.11ac Wi-Fi wireless standard, which offers enough bandwidth for multiple displays and screen resolution of up to 1080p. Use of the 5GHz band for video allows it to coexist with Bluetooth hands-free calls on 2.4GHz, according Broadcom.
Broadcom has also implemented Wi-Fi Direct and Miracast. Wi-Fi Direct lets products such as smartphones, cameras and in this case in-car computers connect to one another without joining a traditional hotspot network, while Miracast lets users stream videos and share photos between smartphones, tablets and displays.
The BCM89335 Wi-Fi and Bluetooth Smart Ready combo chip and the BCM89071 Bluetooth and Bluetooth Smart Ready chip are now shipping in small volumes.
