Consider two cache organization: The first one is $$32$$ $$KB$$ $$2$$-way set associate with $$32$$-byte block size. The second one is of the same size but direct mapped. The size of an address is $$32$$ bits in both cases. $$A$$ $$2$$-to-$$1$$ multiplexer has latency. of $$0.6$$ $$ns$$ while a $$k$$-bit comparator has a latency of $$k/10$$ $$ns.$$ The bit latency of the set associative organization is $${h_1}$$ while that of the direct mapped one is $${h_2}.$$

The value of $${h_2}$$ is

A CPU has five stages pipeline and runs at $$1$$ $$GHz$$ frequency. Instruction fetch happens in the first stage of the pipeline. A conditional branch instruction computes the target address and evaluates the condition in the third stage of the pipeline. The processor stops fetching new instruction following a conditional branch until the branch outcome is known. A program executes $${10^9}$$ instructions out of which $$20$$% are conditional branches. If each instruction takes one cycle to complete on average, then total execution time of the program is

A $$CPU$$ has $$24$$-bit instructions. A program starts at address $$300$$ (in decimal). Which one of the following is a legal program counter (all values in decimal)?

Consider the following program segment. Here R1, R2 and R3 are the general purpose registers.

Assume that the content of memory location $$3000$$ is $$10$$ and the content of the register $$R3$$ is $$2000$$. The content of each of the memory locations from $$2000$$ to $$2010$$ is $$100.$$ The program is loaded from the memory location $$1000.$$ All the numbers are in decimal.

Assume that the memory is byte addressable and the word size is $$32$$ bits. If an interrupt occurs during the execution of the instruction $$''INC$$ $$R3'',$$ what return address will be pushed on to the stack?
