请问spartan3e的执行时间是什么

我是fpga的新手，请你告诉我，什么是spartan3e的执行时间。
如果clk freq是20 mHZ？
你在做什么？

im new to fpga,,can u pls tell me that, what is the execution time of spartan3e. if the clk freq is 20 mHZ?
 
What are you executing?

对于LED开关的基本接口，它会是什么？
在控制器中我们可以说一条指令的执行时间是1.085us。
在PIC 200ns ..就像我要求的那样



以下为原文

for basic interfacing of led switches,what will it be?
in controller we can say that the execution time  for one instruction is 1.085us.
in PIC 200ns.. like that im asking
 

FPGA逻辑与处理器逻辑不同。
处理器顺序执行指令。
FPGA硬件兼容。
为了根据开关设置读取用户开关并打开和关闭LED，“执行时间”大约为10-20nS  - 此组合功能不需要时钟。
如果您希望了解FPGA和FPGA设计，您需要重新定位从处理器到逻辑硬件的思路。
它们是不同的工具。

以下为原文

FPGA logic is different from processor logic.  Processors execute instructions sequentially.  FPGA hardware functions concurrently.  For reading user switches and turning LEDs on and off based on switch settings, "execution time" is on the order of 10-20nS -- and no clock is required for this combinatorial function.
 
If you wish to understand FPGAs and FPGA design, you need to re-orient your thinking from processors to logic hardware.  They are different tools.

大家好 ，

如果clk freq是20 mHZ？
20 mHz时钟的周期为50秒。
所以它会很慢。
当然，你还没有定义“执行时间”的含义，所以这是一个毫无意义的问题。
----------------------------是的，我这样做是为了谋生。

A 20 mHz clock has a period of 50 seconds. So it'll be pretty slow. Of course, you haven't defined what you mean by "execution time" so it's a rather pointless question.
----------------------------Yes, I do this for a living.

十分感谢...
执行时间是否取决于负载（接口设备）？



以下为原文

thank u very much...
is the execution time is depends on the load(intefacing devices) ?
 

>执行时间是否取决于负载（接口设备）？
不，它完全取决于您创建的设计和设计使用的时钟频率。
------您是否尝试在Google中输入问题？
如果没有，你应该在发布之前。太多结果？

> is the execution time is depends on the load(intefacing devices) ?
 
No, it is 100% dependent on the design that you created and the clock frequency that is used by the design.
------Have you tried typing your question into Google?  If not you should before posting.
