Audio Signal Processing System Design Based on FPGA
Abstract: With the extensive application of digital technology, based on the general program DSP chip design is not ideal. DSP chips the first time at this stage of development costs remain high, which is far less than a large number of low-cost ASIC chips, which is one of the advantages of ASIC chips. In this paper, a FPGA realization of the use of AC-Link digital audio processing system design. AC-Link Audio Codec VHDL module system design, after the results of waveform simulation and verification, it will download to the FPGA to achieve. FPGA realization and use of AC-Link sound card D / A conversion functions of the design, fewer resources are needed. This system is used to signal processing system design, we can shorten the design cycle and improve design reliability and efficiency.
