Optimizing an FPGA Application
The following table includes techniques to optimize the usage of the NI 9145 physical memory and increase the compiling speed.
| Optimization Technique | Description |
|---|---|
| Limit the number of user-defined variables | The number of user-defined variables that can fit in the NI 9145 depends on many factors including the number and type of C Series modules used in Scan Mode, the number and type of user-defined variables, and the user logic on the LabVIEW FPGA diagram. |
| Use the smallest data type, if possible | Use the smallest data type for non-constant values to decrease the size and increase the speed of an FPGA VI. |
| Shorten the length of user-defined variable name | The user-defined variable name is stored in the NI 9145 Object Dictionary (OD) after you compile and download the FPGA VI. Shortening the name reduces the usage of the OD table. |
