STA1095中文资料Accordo2双核32位ARM Cortex-R4 / Cortex-M3处理器，具有用于汽车无线电和显示器音频应用的嵌入式SRAM、集成DSP声音子系统、音频ADC和DAC及独立的CAN MCU数据手册ST规格书

描述 Description

Accordo2 is a device that provides a cost effective microprocessor solution for modern automotive car radio systems, with an embedded powerful Digital Sound Processing subsystem, as well as a MIPS efficient ARM Cortex-R4 processor.

In addition, an ARM Cortex-M3 controller is dedicated for real-time Vehicle Interface Processing.

In terms of peripherals, Accordo2 comes with an exhaustive set of common interfaces (UART/I2S/I2C/USB/MMC) which make the device optimal for implementing a feature reach system as well as a cost effective solution.

The solution is bundled with a complete software package, which allows a very fast system implementation.

Accordo2 manages the entire audio chain from analog or digital inputs to analog or digital outputs, including digital audio media decoding, sample rate conversion among various sources, intelligent routing and audio effects / DSP post processing. With its flexible memory configuration, it allows implementing from very low cost systems based on real time OS, scaling up to demanding applications based on Linux OS.

简介

STA1095属于集成电路（IC）的微处理器。由ST制造生产的STA1095微处理器微处理器产品是用于信息和数据处理的集成电路。与主要按照制造商所选术语而视为微控制器的类似产品相比，这些器件有所不同。但是按照传统，微处理器不会在设备内集成工作存储器，不太可能集成混合信号外设，并且可能在更为复杂的软件范式下使用，这些范式涉及使用操作系统来管理多任务同时执行。
