Consider a 3-stage pipelined processor having a delay of 10 ns (nanoseconds), 20 ns, and 14 ns, for the first, second, and the third stages, respectively. Assume that there is no other delay and the processor does not suffer from any pipeline hazards. Also assume that one instruction is fetched every cycle.
The total execution time for executing 100 instructions on this processor is ___________ ns.

For a pipelined $$CPU$$ with a single $$ALU$$, consider the following situations
$$1.\,\,\,\,\,$$ The $$j+1$$ instruction uses the result of the $$j$$-$$th$$ instruction as an operand
$$2.\,\,\,\,\,$$ The execution of a conditional jump instruction
$$3.\,\,\,\,\,$$ The $$j$$-$$th$$ and $$j+1$$ instruction require the $$ALU$$ at the same time
$$1.\,\,\,\,\,$$ The $$j+1$$ instruction uses the result of the $$j$$-$$th$$ instruction as an operand
$$2.\,\,\,\,\,$$ The execution of a conditional jump instruction
