Chapter three introduces the GPIB controller interface function, especially the designing of state machine according to IEEE-488. Chapter four introduces the designing of data channel.
第三章详细阐述了GPIB控制器的十种接口功能及其状态机实现，完全遵循ieee- 488协议规范。第四章对数据通路进行了较为细致的说明。
The engine of data channel is DMA controller. We make use of the Chain ModeDMA strategy, and enhance the bandwidth performance of data.
DMA控制器是数据通道的引擎，这里我们采用了链式DMA的策略，大幅度地提高了硬件传输的带宽。
