Consider a small two-way set-associative cache memory, consisting of four blocks. For choosing the block to be replaced, uses the least recently used $$(LRU)$$ scheme. The number of cache misses for the following sequence of blocks addresses is $$8,12,0,12,8$$

A $$4$$-stage pipeline has the stage delays as $$150, 120,160$$ and $$140$$ nano seconds respectively. Registers that are used between the stages have a delay of $$5$$ nanoseconds each. Assuming constant clocking rate, the total time taken to process $$1000$$ data items on this pipeline will be

Which of the following addressing modes are suitable for program relocation at run time?
$$1.$$ Absolute addressing
$$2.$$ Based addressing
$$3.$$ Relative addressing
$$4.$$ Indirect addressing

Consider the following program segment for a hypothetical $$CPU$$ having three user registers $$R1,R2, $$ and $$R3.$$

Consider that the memory is byte addressable with word size $$32$$ bits, and the program has been loaded starting from memory location $$1000$$ (decimal). If an interrupt occurs while the $$CPU$$ has been halted after executing the HALT instruction, the return address (in decimal) saved in the stack will be
