A microprocessor provides an instruction capable of moving strings of bytes from one place to another in memory. The fetching and initial decoding of instruction take 8 clock cycles. After that, it takes 10 clock cycles to transfer each byte. If the clock rate of the microprocessor is 10 GHz, then the time to transfer a string of 80 bytes is ________. (in nsec) (Assume after each byte transfer interrupt has occurred)
