The LabVIEW FPGA Module Now Includes FPGA
IP Builder
The LabVIEW FPGA Module now includes FPGA IP Builder. You do not need additional licensing to use FPGA IP Builder. You can use FPGA IP Builder to efficiently implement your
LabVIEW algorithms for FPGA targets and to generate FPGA code that meets specific performance requirements. FPGA IP Builder does not require that you place LabVIEW FPGA code inside a single-cycle Timed Loop.
Improvements to FPGA IP Builder
FPGA IP Builder now supports variable-size arrays and case structures. Additionally, FPGA IP
Builder also supports the Last Value, Indexing, and Concatenating loop tunnel modes and the use of conditional terminals when using the Indexing loop tunnel mode.
The LabVIEW FPGA Module Now Includes the FPGA
Compile Farm Server
The LabVIEW FPGA Module now includes the FPGA Compile Farm Toolkit as the FPGA
Compile Farm Server. You do not need additional licensing to use the FPGA Compile Farm
Server on remote machines.
LabVIEW FPGA Compile Cloud Service
Use the LabVIEW FPGA Compile Cloud Service to increase your development efficiency by offloading compile jobs to multiple computers in a cloud environment. Refer to ni.com/ trycompilecloud for information about the LabVIEW FPGA Compile Cloud Service.
Handshaking Interface for FPGA FIFOs
Target-scoped, peer-to-peer, and DMA FIFOs now include a handshaking interface for use within single-cycle Timed Loops. Selecting this interface facilitates communication between upstream and downstream nodes in high throughput applications and saves development time by automatically implementing the four-wire handshaking protocol.
Improvements to the FFT Express VI
You now can process multiple samples from one channel during each cycle using the Single
Channel, Multiple Samples Input Format of the FFT Express VI. If you use hardware that outputs multiple samples per data clock cycle, this option allows you to process the data directly from the FPGA I/O node.
Advanced Settings for Memory Items Using Block
Memory
You now can adjust the latency of the Read (Memory Method) for memory items implemented using block memory. A higher number of cycles of latency results in an increase in internal pipelining, which also can increase maximum frequency of your compiled design.
