GATE IT 2007 | Question: 6, ISRO2011-25
A processor takes $12$ cycles to complete an instruction I. The corresponding pipelined processor uses $6$ stages with the execution times of $3, 2, 5, 4, 6$ and $2$ cycles respectively. What is the asymptotic speedup assuming that a very large number of instructions are to be executed? $1.83$ $2$ $3$ $6$

GATE IT 2004 | Question: 47
Consider a pipeline processor with $4$ stages $S1$ to $S4$. We want to execute the following loop: for (i = 1; i < = 1000; i++) {I1, I2, I3, I4} where the time taken (in ns) by instructions $I1$ to $I4$ for stages $S1$ to $S4$ ... output of $I1$ for $i = 2$ will be available after $\text{11 ns}$ $\text{12 ns}$ $\text{13 ns}$ $\text{28 ns}$

GATE IT 2006 | Question: 41
The data path shown in the figure computes the number of $1s$ in the $32-bit$ input word corresponding to an unsigned even integer stored in the shift register. The unsigned counter, initially zero, is incremented if the most significant bit of the shift register is $1.$ The ... $32, 5, 010$ $5, 32, 010$ $5, 31, 011$ $5, 31, 010$
