GATE CSE 2006 | Question: 43
Consider a new instruction named branch-on-bit-set (mnemonic bbs). The instruction bbs reg, pos, label jumps to label if bit in position pos of register operand reg is one. A register is $32$ -bits wide and the bits are numbered $0$ to $31,$ bit ... $ mask\leftarrow \text{0xffffffff} << pos$ $ mask\leftarrow pos $ $ mask\leftarrow \text{0xf}$

GATE CSE 2006 | Question: 80
A CPU has a $32 KB$ direct mapped cache with $128$ byte-block size. Suppose A is two dimensional array of size $512 \times512$ with elements that occupy $8$-bytes each. Consider the following two C code segments, $P1$ and $P2$. P1: for (i=0; i<512; i++) { for (j=0; ... $P1$ be $M_{1}$and that for $P2$ be $M_{2}$. The value of $M_{1}$ is: $0$ $2048$ $16384$ $262144$
