Frame Buffers :选择vdma缓存几帧图像,这里默认是写通道和读通道都设置相同的缓存帧数,具体设置多少帧合适一般根据应用来定,比如读写带宽相同,想用ddr作为一个乒乓buffer,那就可以设置成2帧,写第一个地址,读第二个地址,写第二个地址,读第一个地址。这里面设置几帧,就要在vdma寄存器配置的时候设置几个帧起始地址。

流式传输帧时很难将配置与特定帧同步,虽然event_frame_started可以参考,但是还取决于帧大小,event_frame_started与配置写入发生之间的延时。 3. 更改配置对转换时序的影响 内核会自动处理相关问题,用户可以随时发送配置信息。 仅当通道为空时,内核才能应用对转换大小的更改。当新的配置信息发送到配置通道,并且该信息包...
