IEEE paper review: Design of Audio Signal Processing and Display System Based on SoC

In this paper, the authors have realised an efficient way of  audio processing by using the functionalities of a designed system on chip. They have used a Xilinx-sync 7000 development platform for the same.

In the market survey before this paper there was only the existence of audio processing techniques divided into two parts namely-Firstly, audio data acquisition and playback based on ARM and Secondly audio data acquisition using DSP or FPGA. ARM has good control but is slow and not good for signal processing whereas FPGA is fast and has parallel processing capabilities and is fast but has very less control.

Hence a system on chip with both features for real time data processing.The system takes in an external input and then at the output we receive rock, pop, classical etc types of music. The ARM part is responsible for control of software and FPGA processes the audio data.

This processed audio data is segregated into different frequency segments and after their gain processing we get different types of music. Hence this hardware software combination on one chip implements clear efficient audio processing techniques.
