USB 3批量传输带宽和串行端口上的诊断输出

我们已经看到了高达110兆字节/秒。一个客户已经看到了高达120 Mb/s，你可能想看看HTTP://wwwyCysP.COM/？APP =论坛和ID；ID＝167和RID＝53351用于相应的修改。
当你说OS/USB堆栈消息时，你是在谈论CyPress驱动程序是针对Windows还是FX3 API堆栈？
当做，

  We've seen upto 110MB/s. One customer has seen upto 120MB/s, You might want to look at http://www.cypress.com/?app=forum&id=167&rID=53351 for the corresponding modifications.
    When you say OS/USB stack messages are you talking about the Cypress driver for Windows or the FX3 API stack?

我在思考嵌入式USB素材（嵌入式USB驱动程序，…）
查看您的编程手册，在将控制权传递给应用程序任务之前，您的嵌入式框架正在做很多事情。如果有一种方法输出一些信息，那就好了，这样我们就可以理解，如果事情出了问题，或者一切正常。

                       I was thinking about the embedded USB stuff (embedded USB driver,...)
    Looking at your programming manual there is a lot of things which your embedded framework is doing before passing the control to our application task. It would be nice if there is a way of outputting some messages which are allowing us to understand if something went wrong or everything was ok.

顺便说一句。。。我很高兴知道你已经看到了120兆字节/秒的传输速率…不幸的是，我并考虑了一些论坛上的评论，其他人也不能用柏树提供的参考设计来重现这些数字。
用哪一个参考设计你测量了120兆字节/秒？
请给我一个主机应用程序和一个FX3固件，能够演示一个设备到主机通信（散出端点）的120兆字节/秒。
在过去，我与FX2一起工作，我在批量输出端点上达到43兆字节/秒没有问题，但是对于所有的CyPress提供的FX3参考设计，我得到的性能远远低于这个数字（板被列举为SS设备）。
请，帮助将不胜感激。
问候，乔尔

  By the way... I'm happy to know that you've seen 120 MBytes/s of transfer rate... unfortunately me, and considering some comments in this forum also other peoples, are not able to reproduce this figures using the cypress provided reference designs.

    With which reference design you measured 120 MBytes/s ?

    Please give me a host application and a fx3 firmware able to demonstrate 120 MByte/s on a Device to Host communication (bulk Out endpoint). 
     
    In the past I worked with the FX2 and I had no problem on reaching 43 Mbytes/s on bulk out endpoints but with all the Cypress provided reference designs for FX3 I get performances which are well below this figure (the board is enumerated as a SS device).
     
    Please, help would be appreciated.

我甚至想知道是否有可能有超过25。30 Mb/s与FX3，只要我们使用DMAYType MyAualSuxOUT从CPU转移到USB…
（为了减少主机上的线程调用频率，我修改了TRAILER以实现4MB的大容量传输，但是它没有改变任何东西……始终保持26 Mb/s的速度，我还修改了批量源库应用程序的来源，以避免CPU将模式复制到DMA缓冲区中。

  I'm even wondering if it is possible to have more than 25..30 MB/s with the FX3 as long as we use  DMA_TYPE_MANUAL_OUT transfers from cpu to u***...

    (I modified the streamer in order to have bulk out transfers of 4MB in order to reduce the thread call frequency on the host but it doesn’t change anything... always 26 MB/s of speed, I also modified the source of the Bulk Source Sink Application in order to avoid the CPU copying the pattern into the dma buffers)
