Advantages of LPM_COMPARE vs. LPM_XOR vs. XOR when comparing two 32 bit numbers

Hi, I need to compare two numbers in a combinational circuit. The inputs are two 32 bit numbers. The output is a single bit and should be "1" when both inputs are equal and 0 when they are not....

Dave and Kaz,

Thanks a lot for your replies. As you noticed from my posting, I am familiar with "traditional" logic circuits, but FPGAs are new to me. Could you advise me on what books/websites to read or courses to take to learn more about how FPGAs are organized and how the synthesis process work? I think if I understand this my FPGA programming skills will improve a lot and I will be able to "encourage" (as Dave put it) the compiler to synthesize my circuit in a way that i consider best for the situation.

I look forward to your comments,

Shoys
