Exploring the Floating Point Performance of Modern ARM …

Some floating-point hardware only supports the simplest operations: addition, subtraction, and multiplication. But even the most complex floating-point hardware has a finite number of operations it can support – for example, no FPUs directly support arbitrary-precision arithmetic. When a CPU is executing a program that calls for a floating-point operation that is not directly supported by the hardware, the CPU uses a series of simpler floating-point operations. In syste… WebOct 16, 2014 · For two, most of today's processors are implemented in a way that addition and subtraction are basically done with the same resources. If there is any difference in execution time, it is subordinate.
