Questions:

How is it controlled?

The processor is controlled by the control unit. The control unit controls all the information flow through the processor and other components. It is the primary component inside the processor. It is considered to be "a brian within a brain". The 32 bit and the 64 bit processors can represent numbers from 0 to something. A 32 bit processor can represent numbers from 0 to 4,294,967,295. A 64 bit processor can represent numbers that are much bigger. This means that a 64 bit processor can calculate much bigger numbers and faster than a 32 bit processor.

What are the common problems for it?

One problem for processors is cache misses. A cache is a temporary storage area where frequently accessed data can be stored for rapid access. Once the data is stored in the cache, future use can be made by accessing the cached copy rather than re-fetching or recomputing the original data, this making average access time much lower. Most of your data and code must come out of the cache or you will be giving up execution speed by a factor of 1000. If you have too much raw code or data it wont fit into a cache. Poor density is the leading cause of cache misses. Sometimes the processor can make bad predictions and this can cause the processor to delay. If the processor writes too much memory, it can store leftovers so some of them get deleted.

What are common solutions for the problems?

Some solutions to common problems is if you have a memory problem is to increase the bus width or speed up the speed clock. The bus is a subsystem that transefers data or power between components. If to much data gets transported, it gets to hard to circumvent. If you have a cache problem you can improve it by getting a larger cache. Larger caches improve the processor by sending fewer requests across the interconnect. If you are going to be removing the processor a lot make sure you dont bend the pins and mess it up.

What are examples for the devices?

Examples of processors are the AMD Opteron 64, Intel Core 2 Duo, Intel Centrino Duo, Intel Centrino Pro, Intel vPro, Intel Celeron, AMD Turion 64, and the Athalon processor. A dual core processor is new. It is essentially two processor cores in one processor. The dual core processor helps increase clock speed. This higher speed comes from more power. The dual core processor need more power to make them work. They made the pipeline in the dual core processor longer which in turn makes higher clock speeds. Its competitor the AMD has a shorter pipeline which allows data to travel through it faster. This allows it to compete with faster processors like the dual core.

Where is there more information on this topic?

Our links have different websites that have the history of processors. We have websites with information on how the processor works and we have some sites that list the best processors of today and some of the earliest ones made.
