Processor


Processor
·         A processor, also known as central processing unit (CPU), refers to the part of a computer that interprets and carries out, or processes, instructions and data contained in the software.
·         Microprocessors are CPUs that are manufactured on integrated circuits, often as a single-chip package.
·         Since the mid-1970s, these single-chip microprocessors have become the most common and prominent implementations of CPUs, and today the term are almost always applied to this form.
AMD64
·         The AMD64, also known as AMD x86-64 or x64, is a 64 bit processor architecture invented by AMD.
·         It is a superset of the x86 architecture, which it natively supports.
·         The AMD64 Instruction set is currently used in AMD's Athlon 64, Athlon 64 FX, Athlon 64 X2, Turion 64, Opteron and later Sempron processors.
·         AMD64 instruction set is a straightforward extension of the x86 architecture to 64 bits, motivated by the fact that the 4GB of memory directly addressable by a 32 bit CPU is no longer sufficient for all applications.
Array Processor
·         Array processor, also called a vector processor, is a microprocessor or computer that is capable of performing simultaneous computations on elements of an array of data in some number of dimensions.
·         Common uses of such processor include analysis of fluid dynamics and rotation of 3D objects as well as data retrieval, in which elements in a database are scanned simultaneously that executes one instruction at a time but on an array or table of data at the same time rather than on single data elements.
Celeron
·         Celeron is Intel microprocessor in the Pentium family marketed as a budget/value CPU line.
·         The first Celeron was based on the Pentium II core.
·         Later versions were based on the Pentium III, Pentium 4, and Pentium-M.
·         The main differences between Celerons and Pentiums are in the areas of bus speed and L2 cache features.
·         Both Pentium-II's and -III's ship with 512kB of secondary (L2) CPU instruction cache, which allows the CPU to store recently used instructions close by and is responsible for much of their high performance.
