Memory & FIFO Functions
Owning Palette: FPGA Module VIs and Functions
Installed With: FPGA Module. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.
Use the Memory functions to access memory on an FPGA. Use the FIFO functions to transfer data.
 | Note This palette is specific to FPGA targets. |
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.
| Palette Object | Description |
|---|---|
| FIFO Clear | Clears a target-scoped or VI-scoped FIFO on the FPGA. You cannot use the FIFO Clear function with DMA FIFOs. To clear DMA FIFOs from the host VI, use the Stop method on the Invoke Method function. |
| 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. |
| Memory Read | Reads from memory available on the FPGA target. Use the Memory Read function in conjunction with the Memory Write function. |
| Memory Write | Writes to memory available on the FPGA target. Use the Memory Write function in conjunction with the Memory Read function. |
| 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. |
| VI-Scoped Memory Configuration | Represents a VI-scoped memory item. Right-click the node and select Properties from the shortcut menu to display the Memory Properties dialog box. Use the Memory Properties dialog box to configure the VI-scoped memory item. |
