Getting Started with FX2LP™
FX2LP Introduction
3.4.3 Booting an FPGA from FX2LP
FX2LP is all about efficient system integration. Figure 7 and Figure 8 illustrate another way FX2LP can save
external logic.

Figure 8 FPGA Boots through FX2LP
FX2LP can be configured to load the FPGA bitstream file from the PC as in Figure 8. This eliminates the need for
a boot memory and enables FPGA updates from the PC.
