디지털 음성 및 영상 처리용 SOC를 위한 ADPCM CODEC 코어의 설계
A Design of ADPCM CODEC Core for Digital Voice and Image Processing SOC
초록
This paper describes the design and implementation results of 40, 32, 24 and 16kbps ADPCM encoder and decoder circuit, based on the protocol CCITT G.726. We verified the ADPCM algorithm using C language and designed the RTL circuit with Verilog HDL. The circuit has been simulated by Verilog-XL, synthesized by Design Compiler and verified using Xilinx FPGA. Since the synthesized circuit includes a small number of gates, it is expected to be used as a core module in the digital voice and image processing SOC.
