Question

The _______ tries to predict what data and instructions will be needed and retrieves them ahead of time in order to help avoid delays in processing.

Answer 1

Answer:

The code prefetch unit

Explanation:

In certain microprocessors such as the Intel 80386, there are about six functional units. They are;

i. the bus interface unit,

ii. the code prefetch unit,

iii. the instruction decode unit,

iv. the execution unit,

v. the segmentation unit,

vi. the paging unit,

Each of the units performs their own different operations.

In the code prefetch unit, data and instructions are retrieved prior to the time they are needed. This helps to reduce processing delays. The code prefetch unit stores these data and instructions temporarily for the next unit which is the decode unit.
