NI LABS GRADUATE - The DSP48E MAC IP Block is a new feature in LabVIEW FPGA 2010 found in High-Throughput Math >> Basic Elements Palette. You should not use this NI Labs download unless you are specifically using LabVIEW 2009 and cannot upgrade.
Introduction
The LabVIEW FPGA DSP48E block provides low level access to DSP48E slices available on Virtex 5 devices. The DSP48E slice provides very high clock rate ALU capabilities including multiply-accumulate and multiply-add. In addition to the high clock rate, the DSP48 also saves fabric logic resources by implementing the operations such as addition within the DSP48 slice instead of normal CLB slices.

Requirements
LabVIEW 2009 and LabVIEW FPGA 2009
Installation
1. Download and unzip the attached LvFpgaDsp48eNodeForVirtex5.zip.
2. Run setup.exe.
3. Restart LabVIEW 2009 if it was running during the installation process.
4. Drop the DSP48 Node off the main palette.
Examples
The following two examples show how the DSP48 can be configured to perform a multiply-accumulate and a multiply-add operation:
<LabVIEW2009>\examples\DSP48E\DSP48E MACC.vi
<LabVIEW2009>\examples\DSP48E\DSP48E MADD.vi
