Multi core Processor

Hi all,

Please provide some information regarding multicore architecture CPU and single core core CPU. Please provide some link to basic architechture differences and the pro and cons of both.


thanks in advance


Regards,

Multi core Processor

what kind of tool set(vendors) available for Multicore?

What kind of architcture is more appropriate for Multicore?

Can you give some references?

Re: Multi core Processor

A multi-core processor (or chip-level multiprocessor, CMP) combines two or more independent cores (normally a CPU) into a single package composed of a single integrated circuit (IC), called a die, or more dies packaged together. A dual-core processor contains two cores, and a quad-core processor contains four cores. A multi-core microprocessor implements multiprocessing in a single physical package. A processor with all cores on a single die is called a monolithic processor. Cores in a multicore device may share a single coherent cache at the highest on-device cache level (e.g. L2 for the Intel Core 2) or may have separate caches (e.g. current AMD dual-core processors). The processors also share the same interconnect to the rest of the system. Each "core" independently implements optimizations such as superscalar execution, pipelining, and multithreading. A system with n cores is effective when it is presented with n or more threads concurrently. The most commercially significant (or at least the most 'obvious') multi-core processors are those used in personal computers (primarily from Intel and AMD) and game consoles (e.g., the eight-core Cell processor in the PS3 and the three-core Xenon processor in the Xbox 360). In this context, "multi" typically means a relatively small number of cores. However, the technology is widely used in other technology areas, especially those of embedded processors, such as network processors and digital signal processors, and in GPUs.

Eg:
AMD's Athlon 64, Athlon 64 FX and Athlon 64 X2 family, dual-core desktop processors, Opteron, dual- and quad-core server/workstation processors, Phenom, triple- and quad-core desktop processors, Sempron X2, dual-core entry level processors, Turion 64 X2, dual-core laptop processors, Radeon and FireStream multi-core GPU/GPGPU (10 cores, 16 5-issue wide superscalar stream processors per core)
