Document Summary
Short answers: (10) (3) most silicon dies are fairly small. Why are they not bigger? (11) (3) what is branch folding? (12) (3) write down the 3-term cpu performance equation developed in class. (13) (6) there are 3 kinds of hazards. List and give brief descriptions of all three. (14) (6) predicated instructions cannot eliminate a branch instruction when that branch is part of what kind of program structure? (15) (14) you are given the following code sequence: Assume there are 8 logical and 16 physical registers. On the left below is the register mapping upon entering the code sequence. Your job is to ll in the mappings after the execution of the addf instruction, including the free list. of. Now, rewrite the code sequence below using the actual physical register names instead of the logical ones. (16) (8) below is a picture of some of the basic components of tomasulo"s algorithm.
