What Does It Mean By 'Dedicated Core For Special Features' & How Does It Works ?

Modern electronics is mostly SoC - system on chip integrating various processing circuits in a single chip. The cores refer to these sections on the chip. For a processor though, the cores are all processing units.

Ofcourse I know all these.
What I want to know is, how a core is selected for single application.
Take for an example : (I forgot which company designed it..maybe it was Exynos 5) There are 5 core processors, 4 cores are dedciated for processing & 1 core for power saving. I wanna know, how it is achieved ?
Now, take this current scenario and assume there is quad core used, When camera is started, how does one core begins to concentrate only on camera or natural lang processing & other still performs processing normal data at normal state.
What's it's advantage over normal processing ?

There are list full of questions, but I would like to know these at first.

Abhishek RawalWhen camera is started, how does one core begins to concentrate only on camera or natural lang processing & other still performs processing normal data at normal state.

This is easier than,calculating and identifying which processor should be used in run time.

If there is no dedicated core then OS scheduler have to decide on run-time which core to select for the process but, if core is dedicated it like Hadcoding that if this process starts use this core.
It makes easy for scheduling thread and low power consuming, stated that those cores will not be used for another process and hence low performance.

Same happen when you run virtual machine and you have to select what are the cores should be dedicated to virtual OS.

Not related to dedicated core but good read <a href="https://www.nvidia.com/content/PDF/tegra_white_papers/tegra-whitepaper-0911b.pdf" target="_blank" rel="nofollow noopener noreferrer">PDF</a>

@#-Link-Snipped-# Thanks for information. Will get back with more questions after reading some good articles regarding dedicated processing.

This is interesting!

sorry

sorry on this one

@#-Link-Snipped-# - it's more about the choice of words you use in asking questions. No one has stopped you from asking questions.
