Estimated computational costs of basic operations, normalised to the cost of the ‘+’ operation. The costs were calculated by running the basic maths operations multiple times in the C software (compiled without optimisations) on Xilinx’s Zynq platform with an Arm processor and Ubuntu Linux and measuring the execution time.
| Operation | Approximate Computational Cost (Relative to the Cost of the ‘+’ Operation) |
|---|---|
| + | 1 |
| - | 1 |
| multiplication | 1.2 |
| division | 3 |
| exp | 15 |
