性价比不断提高如果和1999年的初期相比,FPGA(现场可编程门阵列)成本降低了500倍,容量提升200倍,功耗降低50倍,速度加快了40倍。预计2010年和今天相比,在价格上还将继续降低5倍,容量增大5倍,在每瓦消耗的功耗上有更多的功能,也会增加5倍的速度。在最新的Xilinx Virtex-5的器件里面有10亿以上的晶体管。除了可编程外,还嵌入了多种硬核,诸如最新的PCIe的总线和高速以太网总线,还有高速串行收发器,以及成百的DSP模块。FPGA也非常廉价,举例来说,在Xilinx FPGA里做一个32位的软微处理器,其
Increasing Cost-Effectiveness When compared to the early 1999’s, FPGAs (Field Programmable Gate Arrays) cost 500x less, 200x more capacity, 50x less power and 40x faster. Expected in 2010 compared to today, the price will continue to reduce 5 times, 5 times the capacity increase in power consumption per watt more features, will increase 5 times the speed. There are over 1 billion transistors in the latest Xilinx Virtex-5 devices. In addition to being programmable, there are a variety of hard cores embedded, such as the latest PCIe buses and high-speed Ethernet buses, high-speed serial transceivers, and hundreds of DSP blocks. FPGA is also very cheap, for example, in the Xilinx FPGA to do a 32-bit soft microprocessors, which
