Programming FPGAs using Software via Overlay Processing Engines

强大而廉价的计算推动创新，并在许多领域带来新技术，改善世界各地的生活。 然而，如果我们想继续过去几十年来在计算性能方面的改进速度，那么我们现在必须创新方法来降低计算机的功耗，同时提高其性能-现场可编程门阵列（FPGA）是我们可能克服这一挑战的最有前途的方法之一。

Powerful and cheap computing drives innovation and leads to new technologies in many fields that improve lives around the world. However, if we want to continue the rate of improvement in computing performance seen by the last decades, then we must now innovate ways to reduce the power consumption of computers while improving their performance---and Field-Programmable Gate Arrays (FPGAs) are one of the most promising ways we might overcome this challenge.
