Title:
DEVICE AND SYSTEM AND METHOD FOR PCM AUDIO ACQUISITION ON BASIS OF FPGA
Document Type and Number:
WIPO Patent Application WO/2017/143642
Kind Code:
A1
Abstract:
Provided are a device and method for PCM audio acquisition on the basis of FPGA. In the method, an audio signal on a broadband bus is first acquired, and the acquired audio signal is subjected to FPGA logic processing, then sent to an audio acquisition server for storage. The method reduces the complexity of an audio-recording system; system capacity is large, 32-path acquisition capability is provided, and the audio recording channel is reusable, reducing system development costs.
