A processor has a block transfer instruction which specifies a port address, a count $($number of data to be transferred$),$ and a destination address. Such an instruction takes five clock cycles to transfer each data after the block transfer instruction has been fetched. Assuming that the processor executes instructions at a rate of $1$ MIPS at a clock speed of $10$ MHz$,$ find the time saved due to block transfer instruction for transferring a block of $256$ bytes
