基于SRAM的FPGA在20世纪80年代中期被引入作为实现随机逻辑的高端设备。在接下来的几年里，FPGA在嵌入式系统的设计中发现了许多额外的和新颖的用途。一个例子是快速原型和仿真。最近，可重新配置的硬件被用作ASIC的替代品，具有更短的上市时间和在产品部署后更新硬件的新颖能力。如今，可重配置设备的密度不断增加，以及将它们与可配置片上系统（CSoC）上的处理器、存储器和特殊功能块集成的持续趋势提倡更动态地使用可重配置资源。部分重新配置进一步促进了更高程度的动态性，这种技术允许我们只重新配置一小部分资源，而剩余的资源继续执行。
SRAM-based FPGAs were introduced as high-end devices for implementing random logic in the mid-1980s. In the following years, FPGAs have found a number of additional and novel uses in the design of embedded systems. One example is rapid prototyping and emulation. More recently, reconfigurable hardware is being used as an ASIC replacement with much shorter time-to-market and the novel ability to update hardware after product deployment. Today, the increasing densities of reconfigurable devices and the ongoing trend to integrate them with processors, memories, and special function blocks on configurable systems on a chip (CSoC) advocate more dynamic uses of the reconfigurable resources. A higher degree of dynamics is further facilitated by partial reconfiguration, a technique that allows us to reconfigure only a fraction of the resources while the remaining resources continue to execute.
