An Opening Question An Intel and a Sun/SPARC computer measure their respective rates of instruction execution on the same application written in C Computer A achieves 160 MIPS (Millions of Instructions Per Second) Computer B achieves 200 MIPS Which computer executes the program faster? It depends on the instruction set and compiler (ultimately, the instruction count). Computer B and its mpil m m n m impl (f t ) compiler may use many more simpler (faster) instructions to implement the program thereby increasing its instruction execution rate but saying nothing of overall execution time Shahin Nazarian/EE357/Fall 2009 2
