A CPU instruction set defines
the specific operation a CPU can recognize, and it also determines
the compatibility with programs. For example, programs written
for the x86 instruction set can only support CPU's written for
x86 CPU's. Also, the CPU can also determine the role of CPU
performance. Intel, and other compatible CPU's use the x86 instruction
set, which consists of 147 individual operations. Some instructions
sets are faster and more powerful then others, which helps to
make a CPU faster. Another item very commonly used to help boost
performance is adding L1 and L2 cache memory to a CPU.
The CPU's cache memory is the
basis in which the CPU executes and stores the operations. L1
cache (L stands for level) can help yield the greatest performance
boost. L1 cache is memory that is actually imbedded into the
CPU's core.This type of memory is what the cpu uses to quickly
fetch the simple instructions or calculations that the processor
needs to do. Though usually the cache is not very large. Usually
only between 128 and 512 "k" or kilobytes.
CPU's are not only used in computers.
Other devices like phones and other communication items use
them. The processors used in these devices are not near as powerful
or complex, but still serve their purpose. The computer processor
has proven to be, very useful, and complex device. It helps
us to make computers faster which makes our lives easier when
we need to use one.
