dual core, processor, single core whitepaper

Are there any white paper that explains the meaning of dual core and processors vs cores, etc? Thx in advance

hi,

check this link from wiki :

Re: dual core, processor, single core whitepaper

Hi Trojan!!!!

Single core processor: It is a processor that has only one core, so it can only start one operation at a time. It can however in some situations start a new operation before the previous one is complete. Originally all processors were single core. Multi core processors were introduced later, when increasing the clock speeds further was too hard. These new multi core processors are two processing units combined into one.

Dual Core processor:

A dual-core processor contains two cores, and a quad-core processor contains four cores. A multi-core processor implements multiprocessing in a single physical package. Cores in a multi-core device may be coupled together tightly or loosely. For example, cores may or may not share caches, and they may implement message passing or shared memory inter-core communication methods. Common network topologies to interconnect cores include: bus, ring, 2-dimensional mesh, and crossbar. All cores are identical in homogeneous multi-core systems and they are not identical in heterogeneous multi-core systems. Just as with single-processor systems, cores in multi-core systems may implement architectures such as superscalar, VLIW, vector processing, SIMD, or multithreading.
