What is the function of the Slice and number 4 LUTs in cRIO9104 FPGA?

[TCPIP]

  When I compiled the FPGA VI, the compliation report tell me that there is limitation of the resources pf FPGA, the FPGA that I am using is cRIO9104.  Do you know what is the function of the slice and number 4 LUTs in FPGA? Which FPGA LAbVIEW code need to use these FPGA resources?  And I have attached the compliation report for you as a reference.

  Thank you for your helping!

You've simply got too much code to fit the available resources on that one particular FPGA, just as the error message says. I would take the error message's recommendations, or split up the functionality into two FPGA's.

By the way, LUTs are lookup tables, one way the compiler implements your code. Slices are areas that run independently (general case) of any other slice and how the FPGA achieves true parallel processing.
