在Spartan 6上读取16通道的CMOS矩阵是否可以在SP605板上实现此任务？

您是否打算通过GbE IP实时发送处理过的图像？
如果是这样，请考虑源数据速率与GbE输出通道的有效数据速率之间的差异。
与其要求我们为您设计解决方案，您应该开发自己的顶级框图，其中包含您设计的每个功能块（或流程）。
然后弄清楚每个块的实现方式
在FPGA硬件中（如果适用）
互连（电缆，连接器等）
板级硬件（内存，电源）
在算法（数据压缩，图像处理等）
这将帮助您组织您的想法，识别技术问题，并识别缺少的知识或专业知识。
然后，您应该能够提出更具体的问题，更好地了解需求和依赖关系以及上下文。

以下为原文

Do you intend to send processed images via GbE IP in real time?  If so, consider the difference in source data rate vs. the effective data rate of the GbE output channel.
 
Rather than ask us to design your solution for you, you should develop your own top-level block diagram with each of the functional blocks (or processes) of your design represented.  Then figure out how each block might be implemented

• in FPGA hardware (if applicable)
  
• in interconnect (cables, connectors, etc.)
  
• in board-level hardware (memory, power supplies)
  
• in algorithms (data compression, image processing, etc.)
  

This will help you to organise your thoughts, identify technical problems, and identify missing bits of knowledge or expertise.  Then you should be able to ask more specific questions, with a better understanding of requirements and dependencies and context.

你好。
我是FPGA上图像处理的新手。
我的任务是简单读取CMOS矩阵CMOSIS CMV2000（附件中的数据表）并通过IP协议发送此图像。
对于我的任务，我使用的是SP605开发板和Xilinx ISE / EDK 13.4。
我正在创建新的microblaze项目（这用于IP协议）。
现在我正在研究用于读取CMOS矩阵到DDR内存的自定义外设，然后将其发送到我的笔记本电脑。
在16个并行通道LVDS中读取矩阵。
CLK 480 MHz。
是否可以在SP605板上实现此任务？
如果可能如何使其成为最佳？
对于读取矩阵，我想使用AXI_DMA +我的自定义外设。
我创建测试项目并在内存中写入测试数据，然后将其传输到计算机。
是正确的方法吗？
谢谢。
你所描述的不是初学者的任务。
说真的。您是否考虑过传感器以及SPI配置端口所需的偏置，更不用说高速DDR数据输出？
----------------------------是的，我这样做是为了谋生。

Hello.
I'm newcomer in image processing on FPGA.
My task is simple read read CMOS matrix CMOSIS CMV2000 (datasheet in attach) and send this image over IP protocol.
For my task I'm using SP605 development board and Xilinx ISE/EDK 13.4.
I'm create new microblaze project (this use for IP protocol).
Now I'm working on custom peripheral for read CMOS matrix to DDR memory and then send it to my laptop.
The matrix is read in 16 parallel channels LVDS. The CLK 480 MHz.
Is it possible to implement this task in SP605 board?
Is if it possible how to how to make it an optimal?
While for read matrix I guess to use AXI_DMA+my custom peripheral. I create test project and write in memory test data and then transmit it to computer. Is correct way?
 
Thanks.



 

What you're describing is no beginner task. Seriously.
Have you considered the biasing required by the sensor, as well as the SPI configuration port, not to mention the very high speed DDR data outputs?
----------------------------Yes, I do this for a living.

只是一个背后的计算：
CMOSIS输出= 480 Mbps x 16
SP605 DDR3 RAM = 667 Mbps x 16
因此，只需编写图像就需要大约72％的内存带宽。
明显
您无法使用此路径以全速实时流式传输图像。
如果你只是去
为了拍摄偶然的图像并离线处理，SP605应该足够了。
确保为传感器提供服务的内存端口具有高优先级以避免
丢失图像数据。
祝你好运，

以下为原文

Just a back-of-the-envelope calculation:
 
CMOSIS output = 480 Mbps x 16
 
SP605 DDR3 RAM = 667 Mbps x 16
 
So just writing the image requires about 72% of your memory bandwidth.  Obviously
you can't stream images in real-time at full speed using this path.  If you're only going
to snap an occasional image and process it off-line, then the SP605 should be adequate.
 
Make sure that the memory port that serves the sensor has high priority to avoid
losing image data.
 
Good Luck,

“我的任务很简单”不，不是！
（正如其他人所指出的那样）我最近被一个类比打动了（别担心，瘀伤并不严重）：你的第一个木工项目不会是避暑别墅或华丽的餐具柜。
这将是一个画框，然后可能是一个小桌子。
然后，您将逐渐走向结构性或非常复杂的状态。

模拟，它不会在板上工作。“

"My task is simple "

No it isn't! (As others have pointed out)

I have recently been struck by an analogy (don't worry, the bruising wasn't severe):
Your first wood-working project would not be a summer-house or ornate sideboard. It would be a picture-frame, then perhaps a small table. You would then gradually progress towards something structural or very complicated.
