一种传输实时USB音频的串行接口引擎设计
Design of Serial Interface Engine for Real-Time USB Audio Transmission
摘要
Abstract
Costly MCU is a conventional choice for USB audio device.A new serial interface engine instead of MCU are proposed for efficiently reducing the cost.This design method is based on the FSM (Finite State Machine)theory,The FSM is realized to control the serial interface engine which can process the real-time audio data.The circuit realized in Verilog HDL has been verified by cyclone2 EP2C35 of Altera.The measurement results show that this design is a feasible choice for real-time and high speed USB audio data transmission,with simple circuit but fine universality and transportability.关键词
