Testing computation power of RPi

To test computation power of computer we can we it for do some smart computation then verify it's speed. 

There is one other way to do that we know that video rendering and display takes lots of computation power and to test computer for its speed we can simply run some very heavy game or video. 

Instead of getting into programming and keeping time I tried running 1080p video on RPi. 6.34 GB size movie the matrix. 

Just to give you hint how much computation it did I will calculate bytes calculated per sec. 

Movie is 136min long that is 8160sec. 

6.34 GB is 6492 MB and after dividing by seconds it gives

0.795588 MB that is 815.68KB of content is processed per second that's too much as compared to RPi's capacity. 

6,673,876 operations per second, sounds amazing isn't it??

RPi is optimized with its GPU to perform very well with high graphical demand or fast computations. Because robotics needs lots of operations and very high speed. This GPU can be used to fast robotics computations or to watch 1080p HD videos. :)

Enjoy. Have a nice day. 

Introdution to Raspberry Pi

 

I am not a very good writer but I thought of creating a blog and keep track of things i am trying with everything.

Currently I am working on project  of Raspberry Pi (RPi). 

First and foremost question why Raspberry Pi?

I have a very old machine which has configuration lower than my iPhone. I was lying around for very long time without any use. To make use of that and my head I though of using it for some work which won't need anyone to take care of it and it should work mostly autonomously. There were few ideas of Home automation and home security system using simple webcams.
 It turned out that to use that machine I will have to use very low requirement software and some hardware programming which means I will have to work with USB which are not very developer friendly.

So after going through lots of option and doing good amount of study I decided to use very simple to program computer.

Raspberry Pi works on Linux which i am using for very long time for basic things. It is very popular with simple control simple electronic circuits with it.

I have been using 2 operating systems Xbian and Raspbian.

Xbian converts very small computer in to home theater  like using smart LED TV.

While Raspbian main OS used for RPi as it was mainly designed with hardware. It comes preloaded with things which you can think of doing with RPi you hardly have to install anything. This helped me using RPi without much trouble and i could get anything by just googling.

 What have people tried with RPi?

Everything!!

• Controlling lights, other electronic instruments.
• Robots.
• Weather study machine sent using hot air balloon.
• Sea study machine.
  
• Satellite. 
• Supercomputer.

List is too big to cover but  above list gives sufficent idea.

In next post I will  explain about what have I tried so far and what am I going to achieve with it.
