如何才能动态地将ISERDES2重新配置为不同的序列化比率？

不过。可能会有一些聪明的解决方法。

我正在使用Spartan-6处理带有LVDS的CMOS传感器接口。
传感器可以使用SPI命令配置为10位或12位，这要求ISERDES相应地进行相同的更改。
现在，如果ISERDES2无法动态重新配置，似乎我必须为不同的比特分辨率重新加载不同的比特流。
还有其他想法吗？



以下为原文

I am using Spartan-6 to handle interface to CMOS sensor with LVDS. The sensor can be configured to 10-bit or 12-bit using SPI command, which requires ISERDES do the same change correspondingly. Now if ISERDES2 can not be reconfigured dynamically, it seems that I have to reload a different bitstream for different bit-resolution. Any other ideas?
 
 

不仅需要更改ISERDES2，还需要更改整个数据路径和时钟比率。

It isn't just the ISERDES2 that would need to be changed, but your entire data path and the clocking ratios.

始终将传感器接口设置为12位是否可行，并且在获取10位数据时忽略2个LSB？

Is it feasible to always set the sensor interface to 12-bit, and ignore the 2 LSBs when acquiring 10-bit data?

我希望降低比特分辨率的原因是为了进一步提高帧速率，因此忽略2 LSB不是这里的选择，因为它无助于帧速率。
我知道我需要在比特分辨率改变后更改PLL，但幸运的是，它可以通过动态重新配置来完成。
我认为ISERDES应该有类似的功能，因为它应该不难。
显然我错了。



以下为原文

The reason that I desire to lower bit-resolution is to further increase the frame rate, so ignoring the 2 LSBs is not the option here because it wouldn't help the frame rate.
I know that I need to change PLL after bit-resolution changes, but fortunately it can be done by dynamic reconfigure. I thought ISERDES should have similar function because it should not be difficult. Apparently I am wrong.
