I just wanted to check how it works with 40Mhz defualt clock in a single cycle timed loop in labview fpga. I generated a sine wave in sctl which runs with 40Mhz SCTL. I took another SCTL which runs with 80Mhz clock n i upconverted signal by interpolating with factor 2. I just want to know that first loop each sample takes 25ns(40Mhz) and 2nd loop each sample takes 12.5ns(80Mhz). How can i do this?? I am attaching my FPGA target pic..

That interpolating is likely going to take more than 1 clock cycle to happen, especially at the 80MHz. You might be able to get away with some pipelining.

Why it take mora than a clock cycle? we are adding samplles to signal and after filtering out depending on our pass band frequency..
Can u explain more??
Is decimation also takes more than one clock cycle ??
