Name Homework 1 consider the following: mere are three main instruction types in a certain processor. Memory accesses account for 40% of a instruction, integer arithmetic accounts for 30% of all instructions, and conditionals account for 30% of all instructions. The origi execution time takes 60 seconds. a) Assume memory accesses can be improved by a factor of 2, what is the new execution time? b) Assuming integer arithmetic can be improved by a factor of 3, what is the new execution time
