Owning Palette: Synchronization Functions

Use the FIFO Read and FIFO Write functions to transfer data from one loop to another using FIFOs in an FPGA VI, such as among single-cycle Timed Loops. You also can use the FIFO Write function to transfer data to host VIs using a DMA FIFO.

Note  This palette is specific to FPGA targets and contains a subset of the VIs and functions that are on this palette when you edit a Windows or RT target VI.

The VIs and functions on this palette can return general LabVIEW error codes, specific FPGA Module error codes, or error codes specific to the FPGA target. Refer to the specific FPGA target hardware documentation for information about target-specific error codes.

Palette Object	Description
FIFO Read	Reads the oldest element in an FPGA FIFO and removes the element from the FIFO.
FIFO Write	Writes an element to an FPGA FIFO.
VI-Scoped FIFO Configuration	Represents a VI-scoped FIFO. Right-click the node and select Properties from the shortcut menu to display the FPGA FIFO Properties dialog box. Use the FPGA FIFO Properties dialog box to configure the VI-scoped FIFO.
