电压调节器集成电路

你好，
FX2LP是在SlaveFIFO模式图像传感器接口，显示图像在PC端，我们开发的GUI控制中心应用的帧同步，我们包括8bytes头在FX2LP固件。这个标题时加用框架有效利用FX2LP ISR中断。当框架E有效得到断言的图像传感器，这将被称为ISR。我犯这个8bytes头当它进入ISR函数在批量端点6和一头看起来在控制中心显示连续两头bytes.frame有效之间的图像得到断言每360960字节的image.image传感器具有每秒和752x480 resolution.we 60frames能够接收图像数据在Windows但我们发现有361480个字节的连续两headers.that之间额外的512字节加上因为我们在插入8bytes头手动模式和批量端点缓冲区的大小是512bytes。FX2LP（8051）可以支持水平敏感（低或高），只能是下降沿触发interrupt.currenty我下降沿触发interrupt.that是当框架有效变高到低过渡，我加入这头，最后阿F架有效。我有疑问，对于这头插入时间/位置问题在Windows要我不this.previous框架部分当然也显示在当前帧。因为这头位置的？还是因为512个额外字节即将到来？请帮我解决这个问题了。我附上图片屏的拍摄（视频）。
有时图像转移的发生是由于这些原因不知道这。
1）有些时候没有准确的360960 + 512字节连续两头之间，可能更少或更多
* FX2LP不精确发送360960 + 512字节
* Windows不完全接收360960 + 512字节
* FX2LP中的数据丢失
* Windows侧的数据丢失
*在FX2LP和Windows之间的边界数据丢失。
2）帧有效性未在适当的时间内被断言。
请帮帮我
当做，
吉萨

                                            Hello,
fx2lp is interfaced with image sensor in slavefifo mode .to diplay image on the pc side,we are developed GUI in control center application.for frame synchronisation ,we are included 8bytes header in the fx2lp firmware.This header is added when fx2lp is interrupted by frame valid using ISR.When frame valid is get asserted by image sensor ,this isr will get called.I am commiting this 8bytes header when it enters to the isr function in the bulk endpoint 6 and same header is looked in the control center and displaying image between two consecutive header bytes.frame valid get asserted for every 360960 bytes of image.image sensor is having 60frames per second and 752x480 resolution.we are able to recieve the image data in the windows side.but we found that there is 361480 bytes between two consecutive headers.that is extra 512  bytes are adding because we are inserting 8bytes hearder in the manual mode and bulk endpoint buffer size is 512bytes.fx2lp(8051) can support level sensitive(low or high) and only be falling edge trigger interrupt.currenty i made falling edge trigger interrupt.that is when frame valid becomes high to low transistion,i am adding this header that is at the end of frame valid.i am having doubt regarding this header inserted time/position matters in the windows side.so i am not sure about this.previous frame portion is also displaying in the current frame.is it because of this header posistion?or because of 512 extra bytes are coming ?please help me to sort out this problem.i have attached the screeen shot of images(video stream).

some times imges shifting is happening because of these reasons.we are not sure about this.
1)some times there is no exactly 360960+512 bytes between two consecutive headers,may be less or more
*fx2lp is not transmitting exactly 360960+512 bytes
*windows is not recieving exactly 360960+512 bytes
*data loss in fx2lp
*data loss in windows side
*data loss in the boundary between fx2lp and windows.
2)frame valid is not getting asserted in proper time.


please help me
