Although the CPU needs only a few parts to do its job, it has been modified to
increase its performance. The enhancements are made in order to process data faster.

- One of the weaknesses of the basic CPU was that it was not doing any processing during the time that it fetches an instruction from the computer memory.
To reduce this, a memory storage area was created inside the CPU called Cache or
L1 type Cache. The Cache is very fast, and is used to store information that the CPU
needed to access the most. Level 2 Cache was also developed.

- Now that the CPU has to wait much less for the data to be processed, the speed at which the data can be processed had to be enhanced. To do this, multiple ALUs
(Arithmetic Logic Unit ) were placed on the CPU, so that many more calculation was done each clock cycle.

- In addition, the FPU (Floating Point Unit) was added. The FPU is similar to the ALU, except that it is more advanced. It can handle extremely large and extremely small numbers, allowing greater processing speeds. Also, it can simultaneously process multiple graphics and sounds at a time.
