基于ARM®Cortex®内核,用于汽车收音机的Accordo处理器系列旨在将应用带入全新的集成水平,同时显著降低总体系统成本。

该产品系列提供了各种特性组合,包括音频DSP、图形加速单元、TFT / 触摸屏接口、CAN接口、后视相机和智能手机显示复制接口。

意法半导体的产品提供了完整的交钥匙软件解决方案,其中包括中间件(连接堆栈、文件系统等)和应用软件(媒体播放器、音频解码器、媒体库、iPod库等)。

该系列设备具有完全的可扩展性,从基本的汽车收音机到显示器音频系统,在硬件和软件级别都具有高度的兼容性。

Accordo2 dual core processor for car radio and display audio applications

Accordo2ST’s Accordo2 (STA1095 and variations) processor powers applications ranging from connected car radios to entry display audio systems.

The Accordo2 features a 600-MHz ARM® Cortex®R4 core to process all the needed functions of media management, connectivity and audio decoding.
It is coupled with a powerful DSP for supporting sound enhancement algorithms as well as Echo Noise Cancellation (ECNR) for Bluetooth hands-free phone calls.
It also features analog audio interfaces (inputs, outputs), suppressing the need for external audio codecs.

When the Real Time Operating System is used, applications do not need an external SDRAM to operate, further reducing total system costs (direct code execution “in place” from SQI NOR Flash).

For OEM implementations, Accordo2 devices also integrate a dedicated, isolated ARM® Cortex®M3 core to manage secure CAN connectivity in real time.

With this Accordo2 platform, ST also delivers and supports:

  • a media player
  • all audio decoder formats
  • a media library / metadata management engine
  • a library to control Apple® iPod® devices

The hardware compatibility among various versions of Accordo2 devices allows to use for the use of single scalable PCBs and consequently limit hardware investment costs.
