Document Summary

Suppose we have two implementations of the same instruction set architecture. Computer a has a clock cycle time of. 250 ps and a cpi of 2. 0 for some. Execution time is equal to the number of instructions executed multiplied by the average time per instruction. * average clock cycles per instruction program, and computer b has a clock cycle time of 500 ps and a cpi of 1. 2 for the same program. Big endian: address of most significant byte = word address (xx00 = big end of word) Little endian: address of least significant byte = word address (xx00 = little end of word) Register denoted by $" can be referenced by number (sh-) oro name: - - . - - . - - . Src1 = first register for operation ( source 1 ) Src2 = second register for operation ( source 2 )
