另一方面FPGA也正在朝着类似的目标前进，虽然是从另一个方向。赛灵思和Altera多年来一直在添加软硬核处理器以创建片上系统。FPGA方法一般成本较高，但如果项目需要大量定制逻辑，这就是一种高成本效益的方法。这些器件对于构建ASIC、小批量产品的原型而言极具价值。这类应用的上市时间至关重要，而较大型产品需要持续的硬件灵活性。

微控制器搭配逻辑与FPGA搭配CPU，这两种器件类型都能为现场提供硬件灵活性。一旦基于闪存的器件成为常规，现场升级就会成为标准。最早设计人员只能够升级固件，但现在硬件（逻辑）和固件都能够在现场轻松实现升级。从计算机鼠标到高速网络路由器等设备均能够重新编写设备的固件和硬
