System On Chip(SOC)
When we try to buy new smart phone we often See the specifications like screen size, screen Resolution, battery capacity, Ram, Rom, and so on ..out of these important specification is SOC. some times we neglect what type of SOC used in mobile, Some time we don't even know what variant of SOC used in our mobile..
In Smart mobile launching events or News updates Once in a while we listen these names like
QUALCOMM snapdragon, media Tek MT series, MediaTek helio series, apple A series
Huawei Kirin processor, Samsung Exynos..so on
lets deep dive into the SOC here we try to find what is SOC and why SOC play important role In purchasing of smart mobile..
SOC mean system on chip, when we observe components in the mother board we can see like CPU, GPU, RAM ,ROM and other connectivity modules have you ever wonder these huge Components can be integrated on single chip called system on chip
We know that these elements are user accessible these components are replaced or upgrade Any time while in SOC we cannot change or upgrade the components ..
Here we wish to have computer computing performance in our mobile that should fit with in Our hand ,for this we need to integrate same components in computer with in a single chip..
Advantages of integrating elements on single chip
First the components occupy less space ,less power, decrease system latency decrease heat out Put, we cannot called processor as SOC the reason is we have various components on the SOC
Like DSP (digital signal processing)
ISP (image signal processing)
Temporary storage elements
Parament storage elements
connectivity modules like
Bluetooth ,NFC, FM radio, 4G LTE module ,USB connectivity module, sensor modules ,GPS Modules ,security modules ..and so on
POP (package on package)
Due to less space POP package method was introduced for example storage elements are placed above the modules to decrease size and cost .in SOC we use ARM architecture based
RISC (reduced instruction set computer) . SOC paly an key role in
optimization of software and hardware.
SOC have wide range of applications it is not only used in mobile phones .snapdragon launched a special type of processors for laptops they always connected to internet so they called always connected laptops. By using SOC in laptops we increase the battery capacity Up to 20 hours and even more ..
I think now you got an idea that how important is SOC .
