Are MFLOPS and MIPS related directly?
Only insofar that that the arithmetic logic unit (ALU) in the CPU may be designed to perform both integer and FP calculations. It’s often the case that a processor will have separate integer and FP ALUs and, if this is the case, separate integer (general) registers and FP registers. Of course, there will be conversion/transfer instructions to cope with integer to FP (and vice versa) conversions.
