【摘要】 提出一种采用现场可编程门阵列器件FPGA实现音频处理芯片的方案。首先对FIR滤波器的算法进行了改良,然后采用VHDL语言对音频处理芯片的每个模块分别设计。最后通过计算机软件对该芯片进行仿真,给出仿真波形和仿真结果,证明本芯片的设计达到了预期要求。更多还原

【Abstract】 An audio processing chip is designed by using FPGA in this paper. Firstly, we improve the arithmetic of FIR filter. Then we design each module of the audio processing chip by VHDL. Last, we realize the emulation of this audio processing chip by computer software; prove the audio chip is up to the expected desire.更多还原
