Chipmaker CSR has introduced a new generation of its navigation, multimedia and connectivity solution for in-vehicle infotainment systems as well as mobile Internet and portable navigation devices. The SiRFatlasVI infotainment SoC enables manufacturers to rapidly develop and bring to market OEM and aftermarket products that are able to run multiple functions at the same time for an exceptional user experience.

The SiRFatlasVI SoC offers 3x CPU, 3x graphics and 6x multimedia performance improvements over the previous SiRFatlasV chip at virtually the same BOM cost. These performance improvements will enable the driver to experience more fluid user interfaces, richer map graphics, and concurrent navigation and media playback, the vendor promises.

The new SoC integrates a high-sensitivity multi-satellite GNSS engine that supports the four major global navigation systems: GPS and GLONASS today and Galileo and Compass (with a simple software upgrade) when these systems are operational. The multi-satellite GNSS support offers flexibility and improved satellite acquisition and location tracking in challenging situations like urban canyons.

The integrated ARM Cortex -A9 application processor produces up to 2500 DMIPS, which enables advanced applications and multiple OS's. It is supported by an ARM NEON multimedia accelerator, which is designed to boost multimedia performance by 30 to 40 percent and enables up to 720p decode. Customers can choose to utilise either the new POWERVR 3D graphics accelerator core or rely on the 2D core as a low-cost option.

The integrated memory controller supports 16-bit DDR3/DDR3L and DDR2 memory technology. The SiRFatlasVI SoC supports 60-bit ECC NAND as well as direct boot from SDXC, SLC NAND flash and managed NAND. DDR3 and NAND offer lower total BOM cost, as well as other integrated peripherals.

Integrated I/O and analog functionality, including two USB ports, UART/I2S/SPI/I2C, camera and touch screen interfaces and an audio codec, round out the SiRFatlasVI solution.

The cost, performance and time-to-market advantages afforded by CSR’s SiRFatlasVI device are the direct result of the robust platform solution CSR has developed based on its Synergy technology. With the SiRFatlasVI infotainment platform at its core, this platform enables customers to more quickly and easily develop a complete product based on key CSR location, multimedia and connectivity solutions and supporting software at a highly competitive BOM cost.

In addition to the robust integrated quad-GNSS engine, graphics and multimedia hardware
