NIMCET 2017 Question Paper with solutions

Hit Ratio = 15%
Cache memory time - 10 microseconds
Memory access time = 10 milliseconds
Effective Memory Access Time (EAT) = Hit Ratio
(Cache memory time + Memory access time) + (sign hit) *
(Cache memory time + 2* Memory access time)
EAT - 0.15 (0.01 + 10) + (1-0.15) (0.01 + 2 x 10)
= (0.15) (10.01)+ (0.85) (20.01)
-1.5015 + 17.0085 = 1851 milliseconds
None option is correct.
