Micro Processor

Computer

       Level 1 cache memory, is memory that is included in the CPU itself. Level 2 cache memory, is memory between the RAM and CPU, but not directly on the CPU chip itself. The above photo shows level 2 cache memory on the Processor, beside the CPU. Below are two photos of a CPU (Central Processing Unit). The photo on the bottom is the CPU chip from the outside. 

       The photo on top is a large road map of the inside of the CPU, showing the different areas, and what their function is. See if you can find the areas that fetch, decode, and execute the data. Can you also find the cache areas that store information? The Pipelined Floating Point area, Logic areas, and Super scalar Integer Execution Units area are part of what? Did you guess Arithmetic /Logic Unit? If so, your right! The Control Unit is in charge of decoding, executing, storing, and fetching data. 

       The Control Unit first fetches the data from memory. It then decodes the data so the computer can understand it. Next it has the Arithmetic/Logic Unit process this data by executing it, and storing it back into memory. These 4 steps are what's called the Machine Cycle of a computer. These 4 basic steps are how the computer runs each and every program.
