AKM AK7736B 音频数字信号处理解决方案

AKM公司的AK7736B是高度集成的音频数字信号处理,包括了用于数字音像处理的内部存储器,如环绕声效果处理,时间对准和参数均衡.其DSP部分字长24位,处理速度8.1ns,立体声称两路SRC,包括数字输入/输出接口和MCU接口,主要用在汽车音频系统,汽车导航.本文介绍了AK7736B主要特性,框图和评估板AKD7736B-A功能,框图,布局框图以及电路图与PCB元件布局图.

The AK7736B is a highly integrated audio digital signal processor with integrated 2ch SRC. It includes internal memories for digital audio processing, that allows surround effect process, time alignment and parametric equalizing. Moreover, the AK7736B can process both data and filter coefficients as floating point data so that high accuracy IIR/FIR filter performance can be achieved easily. The AK7736B can operate a hands-free software by AKM as well as sound processing, by programs downloaded via the microprocessor interface.

AK7736B主要特性:

      · Applications: Car Navigations, Car Audio Systems
      · DSP Block
            - Word length: 24-bit
            - Processing Speed: 8.1 ns (2560step/fs; fs = 48kHz)..
