Overview

Product overview

Key product information and technical features.

NI documents the PXI-7954R as a PXI FlexRIO FPGA module with a Virtex-5 LX110 FPGA. The supplied PXI-7954 catalog description matches that model's logic, DSP, block RAM, and DRAM resources, but the catalog name omits the R suffix.

In the documented FlexRIO architecture, the FPGA module provides programmable logic while an attached adapter module defines the physical inputs and outputs. Adapter-specific signal capabilities must therefore be checked separately.

PXI-7954R reference hardware combines a Virtex-5 LX110 FPGA with 64 DSP48 slices.
The reference model provides 4,608 kbits of embedded block RAM, separate from its onboard DRAM.
FlexRIO adapter modules provide the physical I/O interface rather than a fixed analog or digital front end on the FPGA module.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Why does the documentation use PXI-7954R rather than PXI-7954?

NI's module comparison and installation guide identify the matching hardware as PXI-7954R. This catalog retains the supplied PXI-7954 name; check the module label to resolve the missing suffix.

Are block RAM and onboard DRAM the same memory?

No. NI lists 4,608 kbits of embedded FPGA block RAM for the PXI-7954R and separate onboard DRAM consisting of two 64 MB banks.

What determines the module's physical signal connections?

The attached FlexRIO adapter module defines the physical inputs and outputs. Consult the selected adapter's documentation for signal types and pin assignments.
