摘要
一种运行测试G.723.1、G.729等常用低码率语音压缩标准算法的硬件平台的设计方法。使用浮点型DSP TMS320C6713做编解码处理器,EZ-USB FX2系列芯片CY7C68013作为主机通信和引导接口。具有高速、实时、稳定及支持软件升级等特点。
This paper talks about a hardware platform design, which could sustain a series of standards, such as G.723.1, G.729 etc. This platform connects PC and TI DSP TMS320C6713 with EZ-USB FX2 CY7C68013, and provides a bandwidth of 30 MHz. With a float-point DSP, many other algorithms could run on this platform. By integrating the peripheral interface, CY7C68013 provides a stabilized data stream between PC and DSP with its characteristics such as data transfer rates, maximum bandwidth, software update etc.
