Topic: Data Hazards [i and j instructions]

if j tries to read a source before i writes it, so j incorrectly gets the old value. This hazard is the most common type and corresponds to a trust data dependence.

Topic: Data Hazards [i and j instructions]

If j tries to write an operand before it is written by I. The writes end up being performed in the wrong order, leaving the value written by I rather than the value written by j in the destination.

(a)   is a technique in which the hardware rearranges the instruction execution to reduce the stalls, while maintaining data flow and exception behavior.

(a)   is a computer architecture hardware algorithm for dynamic scheduling of instructions that allows out-of-order execution and enables more efficient use of multiple execution units.

(a)   is a register in a computer processor that contains the address (location) of the instruction being executed at the current time
