A basic question concerning multi-core CPU.

A basic question concerning multi-core CPU. Basically, in a microprocessor, there would be a instruction decoding/execution unit, memory (onchip cache) and a ALU. Which of them does the "core" refer to?

Hi singatechno,

Nowadays on multi-Core processors each Core includes decoding/execution unit, memory, ALU and graphics. The information below shows the structure of 6th generation Intel® Core™ processors (code-named Skylake) https://software.intel.com/en-us/articles/an-overview-of-the-6th-generation-intel-core-processor-code-named-skylake Regards,Mike C

Thanks for the reply and the info on Skylake.

In my earlier post, I have missed out the registers set which is a critical part of a processor; and also interrupt processing and I/O interface. Assuming they and what you have mentioned is in a 'core', then a 'core' is almost the complete processor! In fact, its more than that in the case of the Skylake since it also includes the graphical processor. Isn't it?

Miniaturization technology has advanced tremendously indeed, thanks to folks in Intel.

Referring to the Skylake, is it fabricated on a single die or several interconnected ones? What's its packaged size and its max. heat dissipation?

Thanks again.

Hi singatechno,

The processor is fabricated in one die, 6th gen processors are built 14 nannometers. You are right the graphics are included on the processor itself. In regards to maximum heat dissipation, it depends of the type (model) of processor. I suggest you to verify table 5-3 pages 93 and 94. 6th Generation Intel® Core™ Processor Family Datasheet http://www.intel.com/content/www/us/en/processors/core/desktop-6th-gen-core-family-datasheet-vol-1.html Regards,Mike C
