Main memory size = 2¹⁸ bytes

Cache size = 2¹⁵ bytes

Block size = 2⁹bytes

Number of cache lines = Cache size/Block size = 2¹⁵/2⁹ = 2⁶

Therefore, number of comparators required = 2⁶ = 64

Instruction execution in a processor is divided into 5 stages.Instruction Fetch(IF), Instruction Decode (ID), Operand Fetch(OF), Execute(EX), and Write Back(WB),These stages take5,4,20, 10and3nanoseconds (ns) respectively. A pipelined implementation of the processor requires buffering between each pair of consecutive stages with a delay of2 ns. Two pipelined implementations of the processor are contemplated:(i) a nave pipeline implementation (NP) with 5 stages and(ii) an efficient pipeline (EP) where the OF stage id divided into stages OF1 and OF2 with execution times of 12 ns and 8 ns respectively.The speedup (correct to two decimals places) achieved by EP over NP in executing 20 independent instructions with no hazards is ________________.Note:This questions appeared as Numerical Answer Type.
