基于FPGA的语音压缩芯片的设计

Design of Voice Compression Chip Based on FPGA

基于数字信号处理技术、FPGA应用技术和IMA-ADPCM编码算法原理,提出了一种以FPGA芯片为核心,利用DSP Builder开发技术实现IMA-ADPCM标准算法的、高集成度的、应用简单方便的语音编解码器的方法。从硬件、软件、仿真结果等几个方面分别介绍了实现IMA-ADPCM算法的语音编解码器系统。

This paper proposed a new voice codecs method, which was based on DSP, FPGA application technology and the IMA-ADPCM encoding algorithm. The new method regarded the FPGA chip as the core and realized the IMA-ADPCM standard algorithm with high integration, which can be easily and conveniently apply to voice codel. The realization of the IMA-ADPCM algorithm to achieve voice codec has been described from hardware, software, simulator and so on.
