Instructions a second
Instructions a second (most of the time million instructions a second , MIPS ) is a measuring unit.
It is the best unit to establish the comparative ones of power enter processors, even if FAILURES ( Floating-point operations per second ) should not be neglected.
An operation, of Floating-point type for example, is carried out by several instructions:
- displacement
- calculation
- comparison
- …
There exist 2 principal architectures: RISC and CISC, the number of instructions necessary to an operation varies for each one among it.
To compare 2 processors of the same architecture compared to the MIPS is a reliable measurement, that becomes more subjective between architectures.
