Suppose you have a RISC machine with a 2 GHz clock (ie, the clock ticks 2 billion times per second). This particular computer uses an instruction cache, a data cache, an operand fetch unit, and an operand store unit. The instruction set includes simple instructions with the following timings: SET reg. ined; 2 clock cycles LOAD reg. : 3 clock cycles ADD reg, reg: 2 clock cycles ADD reg. inned; 1 clock cycles LOOP Laban; 2 clock cycles Assume that the following code fragment is used to sum the element of a numeric array. initialize sun SET reg, SET reg2, MAX SIZE SET reg), glist ProcessArray initialize loop counter initialize array pointer LOAD regt, [reg] 200 regi, reg reg3, 4 ADD LOOP ProcessArray fetch current List element odd current List element ve array pointer to next element auto-decrement reg2, jump to more if reg2 If the initialization code has already executed (e. the SET instructions have already finished execution) how many array elements can be processed in 4.2 milliseconds (ms)? Round your answer to the nearest integer. Recall that 1 ms-0.001 seconds. Also assume that there are no physical memory limitations, implying that the array can be as large as desired.
