Suppose you have a RISC machine with a 2 GHz clock (i. e., 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, immed 2 clock cycle
loop label 3 clock cycles
add reg, immed 1 clock cycle
add reg, reg 3 clock cycles
load reg, mem 3 clock cycles

Assume that the following code fragment is used to sum the element of a numeric array. If the initialization code has already executed (i. e. the SET instructions have already finished execution) how many array elements can be processed in 2.4 ms?
