1·Some designs might use an external microcontroller to load the bitstream from an external storage device.
一些设计可能使用外部微控制器从外部存储设备加载比特流。
2·Unfortunately, when you do this, XPS will check the dependencies and try to build the bitstream before downloading it.
不幸的是，执行此操作时，XPS会检查依赖项，并试图在下载比特流之前构建它。
3·If you use the CPLD method of configuring the FPGA, you can store both the FPGA bitstream and the required code in a single NOR flash chip; it's probably the simplest system design.
如果使用CPLD方法配置FPGA，则可在一个NOR闪存芯片中存储fpga比特流和所需的代码；这可能是最简单的系统设计。
