怎么在Spartan 3E中存储一个恒定的1 MB大比特流并将其读出

G，
这取决于电路板，闪光灯以及配置（连接）的方式。
你在和哪个董事会合作？
一旦我们知道了，那么我会查看该板的文档，特别是“基础系统构建器”示例设计。
然后我会尝试一个接近你想做的BSB设计示例，在你能够在工具中复制它之后，我会考虑为它添加另一个接口（读取和写入flash）。

g,
 
It depends on the board, the flash, and how it is configured (connected).  What board are you working with?
 
Once we know that, then I would look at the documentation for that board, and specifically the "base-system builder" example designs.  Then I would run through an example BSB design that is close to what you want to do, and after you are able to replicate it in the tools, I would look at adding another interface to it (to read and write the flash).

我正在使用Spartan 3E入门套件板。
我用USB线编程。
根据此处列出的规格（http://www.xilinx.com/products/boards-and-kits/HW-SPAR3E-SK-US-G.htm），它说Xilinx器件：Spartan-3E FPGA（XC3S500E-4FG320C）
）CoolRunner™-II CPLD（XC2C64A-5VQ44C）平台闪存（XCF04S-VO20C）时钟：50 MHz晶振时钟振荡器内存：128 Mbit并行Flash16 Mbit SPI Flash64 MByte DDR SDRAM XCF04S-VO20C有4Mb闪存，还有另外两个条目
说128 Mbit并行Flash16 Mbit SPI Flash。
我用哪一个呢？



以下为原文

I am using the Spartan 3E starter kit board. I program it with a USB cord. From the specifications listed here (http://www.xilinx.com/products/boards-and-kits/HW-SPAR3E-SK-US-G.htm) , it says

Xilinx Devices:
Spartan-3E FPGA (XC3S500E-4FG320C)
CoolRunner™-II CPLD (XC2C64A-5VQ44C)
Platform Flash (XCF04S-VO20C)
Clocks: 50 MHz crystal clock oscillator
Memory:
128 Mbit Parallel Flash
16 Mbit SPI Flash
64 MByte DDR SDRAM

The XCF04S-VO20C has 4Mb flash memory while there are two other entries saying 128 Mbit Parallel Flash
16 Mbit SPI Flash. Which one do I use for this?

G，
SPI闪存可能是一个更容易使用这个板的接口。

g,
 
The SPI flash might be a much easier interface to usemon this board.

嗨奥斯汀，谢谢你的帮助。
我想我将能够弄清楚如何使用基本系统构建器向导在Flash中存储一个bitream。
如果我理解正确，我基本上是使用这个基本系统构建器向导在FPGA上构建自己的微控制器。
现在我想调制这个我编写了另一个verilog模块的比特流。
我可以用这个基于fpga的微控制器以某种方式连接那个verilog模块吗？
我该怎么用？
我能阅读的一些术语可以帮助我实现这一目标会有所帮助。
谢谢

Hi Austin, 
Thanks for all your help.
I guess I will be able to figure out how to store a bitsream in the flash by using base system builder wizard. If I have understood right, I am basically building my own microcontroller on the FPGA with this base system builder wizard.  
 
Now I want to modulate this bitstream for which I have written another verilog module. Can I interface that verilog module somehow with this microcontroller built on the fpga? What do I use for that? A few terms that I could read about that would be help me achieve this would be helpful.
Thanks
