Answered: In a pipelined architecture Static branch prediction is used with branch taken assumption. Assume that 30% of the instructions executed for a program are branch instructions. Each stage has 2 nsec delay. Average Execution time(in nsec) if 80 % of the instructions are taken?

It is given $30$% of the instruction are branch instruction. It is using static branch prediction which always assume branch is taken. branch was taken =$80$% of the time So,20% of the time branch was not taken but due to static branch prediction it assume branch was taken but it doesn’t .So this much time contribute to branch penalty. Now Assuming branch is taken in EX-stage and the target branch instruction will be fetched in the next IF stage – so $2$ stall cycles per conditional branch taken. So,Branch penalty=$2$ . So, average CPI=$1+0.3*0.2*2$=$1.12 $cycle. Now as it is using… [...]

consider a cache organization employing a line of 64B and main memory that requires 40ns to transfer a 2B word. What is the minimum average number of times a cache line must be made dirty for write-back policy to be more efficient than write though policy, for any linne which is written at-least-once

Answered: Made easy || Database

Maximum number of candidate keys for a relation can be given by:$\binom{n}{\left \lceil n/2 \right \rceil}$. For example R(A,B,C,D) have AB,BC,CD,AD,BD .Here A is fixed in any candidate key, so for other 5 attributes we have $\binom{5}{\left \lceil 5/2 \right \rceil} = 10$ keys. So, answer is 10.
