Raspberry Pi
Introduction
• The Raspberry Pi is a credit-card sized
computer
• It can be plugged into your TV and a
keyboard, and can be used for many of
the things that your average desktop
does - spreadsheets, word-processing,
games and it also plays high-definition
video.
Introduction
• measuring
approximately 9cm
x 5.5cm
History
The Raspberry Pi is the work of the Raspberry Pi
Foundation, a charitable organisation.
UK registered charity (No. 1129409), May 2009
 It's supported by the University of Cambridge
Computer Laboratory and tech firm Broadcomm
Motivation
Computer science skills increasingly important
Decline in CS student numbers
Access to computers
Computers are the tool of the 21st century
Computer Science is concerned with much more
than simply being able to use a computer.
Children should understand how they work and
how to program them
What is Raspberry Pi?
• The Raspberry Pi is a fully featured micro-
computer squashed onto a circuit board
measuring approximately 9cm x 5.5cm.
Features
• Ultra low-cost (Model A $25, Model B $35)
• Ultra low-power ~1W
• Credit-card sized, fanless, instant start-up
• Complete easy-to-program computer
Features
• Provide a fun environment for experimenting
with programming and electronics
• Inexpensive, simple, open and easy to
maintain computer for schools
• Fun computer for children to experiment
with at home(programming, robotics, etc...)
Technology
• The Raspberry Pi has a Broadcom BCM2835
system on a chip (SoC),which includes an
ARM1176JZF-S 700 MHz processor
• Video Core IV GPU
• originally shipped with 256 megabytes of RAM,
later upgraded to 512MB.
• It does not include a built-in hard disk , but uses
an SD card for booting and long-term storage.
Hardware
• 10/100 BaseT Ethernet socket
• HDMI socket
• USB 2.0 socket
• RCA video socket
• SD card socket
• Powered from microUSB socket
• 3.5mm audio out jack
• Header footprint for camera connection
Operating System
• Linux on a bootable SD card
• Fedora
• Raspbian
• Debian
• ArchLinux ARM
How to make it work!
Programming
• By default, supporting Python as
the educational language.
• Any language which will compile
for ARMv6 can be used with the
Raspberry Pi.
Price
• Model A - $ 25
• Model B - $ 35
• Why so cheap ?
• SoC - System on a chip, a computer on a
single low voltage chip
• Linux OS
Applications
• Can be used for making super computers
Applications
Raspberry Pi Medical Device Input Shield
Applications
• Solar Raspberry Pi Power Pack
Applications
• Voice-Activated Coffee Machine
• Raspberry Pi Dynamic Bike Headlight
Prototype
Applications
• It can make your Old TV in to a smart TV. (You can
play Videos, 3D Games, Music, Browse Internet and
much more.
• Raspberry Pi can Act as Full HD 1080p Media Player.
• Its a Mini Computer which just cost Rs.2,350/-
• You can connect a Monitor, Keyboard and Mouse
and use it as a normal computer.
• Its Graphics Capabilities is better than Apple
Products.
Raspberry Pi Vs Akash
• Aakash is a low-cost tablet, and Raspberry Pi is an
ultra-cheap, customizable computer.
• Both tech innovations have education and
economy as their central goals.
• Aakash could fundamentally change the way Indian
students and most of rural India connects with the
Internet.
Raspberry Pi Vs Akash
• The Raspberry Pi, directed at budding computer
engineers in the U.K., could alter the way the
next generation thinks about coding and building in
the computer universe.
• Both the Aakash and Raspberry Pi run on ARM-
based processors, the British processor that runs
the vast majority of the world’s mobile phones,
smartphones and tablets.
Raspberry Pi Vs Akash
• The first generation Aakash is said to run an ARM
11-based processor from Conexant running at
366Mhz.
• The Raspberry Pi uses an ARM 11-based
processor from Broadcom running at 700Mhz plus
a separate graphics processing unit.
• The processor in the Raspberry Pi has about twice
the graphics performance of the iPhone 4S and
even bests Nvidia’s Tegra 2.
Raspberry Pi Vs Akash
• The Raspberry Pi can connect to a television or a
computer monitor via the commonly used
composite RCA and HDMI video interfaces.
• Akash tablet runs on an Android 2.2 OS.
• The Raspberry Pi computer will run a number of
Linux-based operating systems including Red Hat’s
Fedora as well as Debian, the basis for the popular
Ubuntu distribution, and Arch.
Disadvantages
• It does not have a Hard Disk associated with it for
permanent storage pf files,we have to connect one
externally or have to use SD card for the purpose.
• The RAM is a POP package on top of the SoC, so
it’s not removable or swappable.
• There is no Real time clock associated with the
board.Adding an RTC is expensive. You can add
one yourself using the GPIO pins.
Future developments
● Tablet version
● Interesting low-cost screen technologies
emerging
● Brambles! (Networks of Raspberries)
Raspberry Pi 2020
● Exploit process scaling and keep price
constant:
– 8 cores, improved GPU, 8GB main memory
– WiFi, camera, matchbox sized case
– holographic laser projector, virtual keyboard
– FPGA logic on main SoC, high speed links, ….
– < $25

Editor's Notes

  1. The ARM1176™ applications processors deployed broadly in devices ranging from smart phones to digital TV&apos;s to eReaders, delivering media and browser performance, a secure computing environment, and performance up to 1GHz in low cost designs. The ARM1176JZ-S processor features ARM TrustZone ®  technology for secure applications and ARM Jazelle® technology for efficient embedded Java execution.
  2. A field-programmable gate array ( FPGA ) is an integrated circuit designed to be configured by a customer or a designer after manufacturing—hence &quot;field-programmable“FPGAs contain programmable logic components called &quot;logic blocks&quot;, and a hierarchy of reconfigurable interconnects that allow the blocks to be &quot;wired together&quot;
