Differences between Host and FPGA VIs

The resources on a host and an FPGA make each target better suited to different types of programming tasks. The programming objects available in a host VI and an FPGA VI vary to match to the purpose of the VI. This document-sensitive variation makes it easier and quicker for you to create code that is compatible for the target you want a VI to run on.

The following table describes the differences between a host VI and an FPGA VI.
