SiRFatlasVI SoC全面分析

产品概述

As the latest infotainment SoC from CSR, SiRFatlasVI is designed to enable user experience of advanced graphics, location and connectivity on mainstream automotive dashboards at competitive overall cost and fast time-to-market, with pre-optimized GNSS, Bluetooth and Wi-Fi.

特点与优点

Enables greater user experience at similar BOM cost compared to previous-generation Atlas product: 3x CPU DMIPs, 3x graphics and 6x multimedia performance improvement, enabling the driver to experience more fluid user interfaces, richer map graphics, and concurrent navigation and up to 720p media playback Integrated multi-satellite GNSS capabilities support all global navigation systems, providing flexibility and improved satellite acquisition and location tracking in challenging situations like urban canyons. Support for industry-leading dead-reckoning technologies is also provided Value leadership: powerful performance, competitive BOM cost, direct local R&D support Supports concurrent multiple user scenarios on in-vehicle infotainment system, PND, MID and other modern multifunction devices Short time-to-market at low overall cost: High SoC integration, simplified hardware design including a PCB-friendly 0.65-mm ball pitch package, fully qualified BSPs with location and connectivity platform solutions, plus local engineering support
