Investigation and creation of a hardware and software IP that can implement USB 2.0 Audio to I2S conversion

This project aims at designing and creating a hardware and software Intellectual Property that can implement USB to I2S conversion. I2S is an interface which is widely used for audio data transmission. With this design, audio data can be directly transmitted from USB interface to audio signal processing integrated circuits. ESS Technology is a leading semiconductor company specializing in offering comprehensive, multimedia solutions for audio and video applications. This USB Audio 2.0 System would reduce the cost of purchasing USB controller processors from other manufacturers, and increase the diversity of future products. Another benefit is to provide more flexibility and compatibility to accommodate different kinds of audio application scenarios. This simplified and economical USB audio solution can be a cornerstone for all the USB audio products in the future.
