什么是用于切换FPGA并执行操作的最小能量，执行然后关闭/空闲？

显然，取决于操作是什么。
如果操作是“将引脚C12设置为逻辑1”，那么CoolRunner II可能是最低功耗的Xilinx选项。
您不会通过配置浪费电源（因为CRII是基于闪存的），并且您不会浪费静电，因为那里几乎没有任何电路。
如果操作是“识别UQHD视频3000小时内的所有对象”，那么我怀疑最低的总能耗将是最小的Kintex UltraScale +，它可以满足其中所需的处理硬件。



以下为原文

Depends what the operation is, obviously.
 
If the operation is "set pin C12 to logic 1", then a CoolRunner II is likely to be the lowest power Xilinx option. You don't waste power with configuration (because the CRII is flash-based), and you don't waste static power because there's hardly any circuitry in there.
 
If the operation is "identify all objects in 3000 hours of UQHD video" then I suspect the lowest total energy consumed will be the smallest Kintex UltraScale+ that can fit the required processing hardware in it.

非常棒，13μA静态电流和125Mhz 50mA x 3.3V，256个宏单元，每单位约20美元
我想知道1个Artix7和210K Logiccells需要多少个coolrunner芯片，每个单元约50美元
XC7A50T具有ICCINTQ + 120 ICCAUXQ + 40 ICCOQ + 40 mA每组ICCBRAMQ + 60 mA~500mW正常工作，处于暂停状态时它消耗多少功率？
在合成方面，我的设计几乎没有触发器
我可以简单地综合和比较抓取并使用Xilinx功耗估算器（XPE）工具我很抱歉我的问题我应该看看DC和AC开关特性数据表，然后合成然后使用XPE。
无论如何，我都感谢你的帮助

It is really great, 13 μA quiescent current and on 125Mhz 50mA x 3.3V for 256 macrocells and around 20$ per unit
 
I wonder how many coolrunner chips I need for 1 Artix7 and 210K Logiccells and around 50$ per unit
the XC7A50T has ICCINTQ + 120 ICCAUXQ + 40 ICCOQ + 40 mA per bank ICCBRAMQ + 60 mA ~ 500mW  in nomal operation and when in suspended state how much power does it consume?
 
in term for synthesis my design has hardly no flip flops
 
I can simply synthesise and compare the seize and use the Xilinx Power Estimator (XPE) tools I am sorry for my question I should have just looked at the DC and AC Switching Characteristics Datasheets, then syntesise and then use the XPE.
 
I'm all set thanks for the help anyways
