摘要
为了将采集的数据高速传输到上位机,充分利用TMS320C5416的HPI接口与EZ-USB FX2的GPIF控制器模式,设计了一种高速数据采集系统,并在VC++软件环境下利用Win32函数DeviceIoControl(),实现了与下位机的通信。本数据采集系统支持USB2.0协议,数据传输速度最高可以达到480 Mbit/s,数据采样率高,数据处理能力强。
A system of high speed data acquisition is designed, in which HPI interface of the TMS320C5416 and GPIF controller mode of the EZ-USB FX2 are utilized. The function DeviceIoControl（） of Win32 in VC＋＋ is also used to realize communication between PC and data acquisition. This system supplies USB2. 0 protocol, and it can transfer data at 480Mbit/s. It also improves efficiently the performance in data sampling and data processing in practice.
