Car SoC targets infotainment apps

Renesas Electronics Corp. has debuted an automotive SoC intended to address the growing integrated dashboard and information device market demands. Capable of delivering more than 12,000 DMIPS and twice the graphics performance of previous generation high-end devices, the R-Car M2 supports high-definition navigation, real-time voice control and other features to provide enhanced connected user experiences within the car, described the company.

With the latest member of its R-Car series, Renesas aims to expand and reinforce the ecosystem led by the R-Car Consortium, the partner programme of OS and software providers. According to the firm, the R-Car M2 SoC exceeds the previous high-end R-Car H1, with more than three times the enhanced CPU and nearly six times the graphics capacity and three times the memory bus function compared to the previous R-Car M1. In addition, the software package uses the software developed on R-Car H2.

Automotive information devices today integrate IT such as cloud computing with smartphones, and functions for safety such as around-view monitoring with onboard camera to offer drivers higher security, safety and conformity. As integrated dashboard systems improve and become more and complex, auto makers require higher performance, function and product quality. This results in higher difficulty in hardware/software development, rising development cost, longer development period and difficulty in maintaining product quality.

The 2+1 structure of two CPUs—Cortex-A15 and SH-4A—realises more than 12,000 DMIPS. Simultaneous operation of high-end functions such as high-definition navigation, intelligent browsing or precise speech recognition is compatible with real-time responses to drivers' requests.

The highest performance is realised by upgrading to the PowerVR SGX544MP2 from Imagination Technologies and by raising the operating frequency from 250MHz to 520MHz, stated the firm. The system supports high-resolution/HD display as well as simultaneous drawing to multiple displays.

The total cost is minimised by integrating functions required in next-generation, mid-range automotive information device in one chip. The R-Car M2 shares not only the function IP but also the memory map with R-Car H2, to unify the driver and middleware, and also software development and control to R-Car H2/M2, which contributes to the reduction of development cost and development time.

The evaluation board for SoC functions was previously used in software development with the partners. A low-cost software development board prepared with 1/5 the cost of the previous board is in development, concentrating on functions for software development by the partners. The board is to be released in December 2013. Renesas offers packaged standard software such as driver or middleware to support customer development of application or system integration in cooperation with R-Car Consortium partner companies.

Samples of the Renesas R-Car M2 SoC are available, equipped in an 831-pin FCBGA package. Mass production is scheduled to begin in June 2015 and is expected to reach a combined production volume of 500,000 units per month by June 2016. A low-cost development board implementing the R-Car M2 will be available from December 2013.
