Pocket ARM-Based Computers, A Revolution

1 comment
UK based Raspberry Pi Foundation have developed Credit Card sized arm-based computer. Being so small in size which is perfectly made to fit inside pockets is aimed for teaching computers at schools for children.

The initial product would work on 700 MHz frequency (can be overclocked to 1 GHz ) with 256 MB of RAM. The second variant would have double size RAM, an additional USB Port & a LAN Port.
In both the variants there would be no hard drive, both of them will use SD Cards for Storage.

The main USP of these CPU are that they are available at very cheap cost. 25$ for the first variant & an additional 10$ for the second.

It uses Linux-based Kernel for its operating system. RASPBIAN is the operating system which is developed to be fully compatible with the Raspberry Pi hardware.
Raspberry Pi is the first ARM-based multimedia SoC with fully Functional, vendor provided fully open source drivers. This means everyone can develop application as well as can modify the OS.

The underlying architecture is the same as of the ARM's with an additional Broadcom's Videocore IV GPU that would be loaded at the boot time as a form of image from the SD card. The System would be integrated on a single board and it will use Broadcom BCM2835 Chip.

The primary variant will work on 2.5 W Rating & the second variant (model B) will work on 3.5 W Rating.

Being the one of its own device, it would be compared with the cheapest competitor in the market, i.e. Akash Tablets.

However the device has been released by February, 2012 for the primary variant, the dates are not disclosed for the availability of the higher model (Model B).

Do give views for the awsm invention, suggestions or any tweeks !!

  1. I am not in favor of this new exam pattern.Its totally an injustice to the regional board aspirants.Its a well known fact that CBSE's marking system is comparatively easier than other regional boards.So,definitely CBSE candidates will score more in ISEET
