StreamIt Number Calculations

No StreamIt numbers were available.

C Code Single Tile Raw Number Calculations

The GSM Application was too large to fit on a single RAW tile.

C Code Number Calculations

Performing 1 iteration at 14016000 outputs/iteration.
Runtime for 1 iteration is 4.065 seconds.

Number of cycles per iteration: 1 iterations/ 4.065 second * 14016000 outputs / 1 iteration * 1 second / 2.2*10^9 cycles * 10^5 cycles = 156.726 outputs / 10^5 cycles.
