What is a Dual Core Processor ?

• Dual-core refers to a CPU that includes two complete execution cores per physical processor.
• It has combined two processors and their caches and cache controllers onto a single integrated circuit (silicon chip )
• Multi-core is similar to dual-core in that it is an expansion to the dual-core technology which allows for more than two separate processors.
• Dual-core refers to a CPU that includes two complete execution cores per physical processor.
• It combines two processors and their caches and cache controllers onto a singleintegrated circuit (silicon chip).
• It is basically two processors, in most cases, residing reside side-by-side on the same die.
• Dual-core processors are well-suited for multitasking environments because there are two complete execution cores instead of one.
• Each with an independent interface to the front side bus.
• Since each core has its own cache, the operating system has sufficient resources to handle most compute intensive tasks in parallel.

Dual Core Processor  ADVANTAGES: –

• Performance is faster than single-core processors.
• Able to divide information for processing by multiple units.
• Core processor uses slightly less power than two coupled single-core processors Multi-core chips also allow higher performance at lower energy.
