怎么设计一个带有两个视频输入的系统

你好，
我需要设计一个带有两个视频输入的系统。
我需要存储来自2个不同摄像机的2个视频帧并将它们存储在同一个RAM存储器中。
然后我需要处理两个图像并在VGA屏幕上显示它们。
我需要在两幅图像之间做一些融合。
实际上我对建筑的概念很困惑。
我将使用微型光纤来配置2个摄像头。
我将以30Hz的pclk接收30Hz的图像，每个图像都有自己的CLK，我使用触发器来同步它们。
然后我将为每个视频流使用一种带有双时钟FIFO的模块。
我将使用PCLK在每个fifo中写入，我将使用100MHz的SYS_CLK读取FIFO，然后我将在内存中写入。
然后将有另一个模块，它将是两个图像之间的融合。
我的问题是：
我必须使用哪种接口将相机连接到我的模块？
FSL？
我知道xilinx中存在点对点连接。
我已经用altera做了同样的事情，我使用了Avalon Stream接口。



以下为原文

Hello,

I need to design a system with two video inputs.

I need to store the 2 video frames that comes from 2 different cameras and store them in the same RAM memory.

Then I need to process both images and display them in a VGA screen. I need to do somekind of fusion between the 2 images.

Actually I am confused in the conception of the architecture. I will use a microblaze to configure the 2 cameras.

I am going to receive the images at 30Hz with a pclk of 30MHz, each image has his own CLK, I use a trigger to synchronize them.

Then I will use a kind of module with dual clock FIFO for each video  stream. I will write in each fifo with the PCLK, and I will read the FIFO with my SYS_CLK of 100MHz and I will write in memory.

Then there will be another module that will be the FUSION between the two images.

My question is:

Which kind of interface I must use to connect the camera with my modules? FSL?

I understand that there are point to point connections in xilinx,.


I have already done the samething with altera and I used an  Avalon Stream interface.
