Use the FPGA memory item interface to use DRAM in the same way that you use block memory and look-up tables (LUT). DRAM memory items appear in the Project Explorer window under the FPGA target. The FPGA memory item interface allows you to partition the physical DRAM banks into multiple memory items. You can create target-scoped or VI-defined memory items. For more information about these different memory items, refer to the Using FPGA Memory topic.
Complete the following steps to configure DRAM with FPGA memory items.
|Note A memory item targets a single DRAM bank. If you only select one memory item, this memory item can be as large as the entire bank. You can use memory items to divide the full DRAM space into smaller memories that you can access independently from different sections of the LabVIEW FPGA code. The figure below shows the logic that LabVIEW generates to provide access to a DRAM bank.|
|Note If you use a Memory Method Node in a single-cycle Timed Loop, make sure the corresponding arbitration option is Arbitrate if Multiple Requestors Only or Never Arbitrate.|
