下面这段话可以解释为什么FPGA功耗大。
In an FPGA, all of the routing and look-up table (LUT) configuration is done via SRAM cells. This means that the majority of the transistors in a typical FPGA are involved with the configuration rather than the actual logic function. Any given design implemented in an FPGA will require many more active transistors (estimates are in the 5x-10x range) than that same design implemented in a metal-programmed technology. In today’s small process geometries (90nm, 65nm, and 45/40nm), oxides are so thin that these transistors leak – a lot. All those extra leaky transistors mean that your design will consume many times (5x-10x maybe?) more static power than its metal-programmed counterpart.

手机都有摄像头了,这种东西没多大用处。

这个小东东不错啊!很适合于大众用户使用,特别是适合大学生.假如有哪个厂商生产我第一时间就想去买一款.
既然是低端的小型产品,只要在成本访面能有所改善,一定是个赚钱的东东.
