Raspberry pi
The Raspberry Pi is a credit-card sized computer that can connect to keyboards, monitors and TVs to function similarly to a desktop computer. It was developed by the Raspberry Pi Foundation in the UK to inspire teaching of basic computer science in schools and develop interest in programming. While low in cost at $25-35, the Raspberry Pi runs Linux and can be used for a variety of applications including robotics, programming practice and basic computing tasks.

- 5. Motivation Computer science skillsincreasingly 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
- 6. What is RaspberryPi? • The Raspberry Pi is a fully featured micro- computer squashed onto a circuit board measuring approximately 9cm x 5.5cm.
- 7. 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
- 8. Features • Provide afun 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...)
- 9. Technology • The RaspberryPi 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.

- 20. Applications • It canmake 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.
- 21. Raspberry Pi VsAkash • 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.
- 22. Raspberry Pi VsAkash • 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.
- 23. Raspberry Pi VsAkash • 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.
- 24. Raspberry Pi VsAkash • 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.
- 25. Disadvantages • It doesnot 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.

Editor's Notes
- #10 The ARM1176™ applications processors deployed broadly in devices ranging from smart phones to digital TV'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.
- #28 A field-programmable gate array ( FPGA ) is an integrated circuit designed to be configured by a customer or a designer after manufacturing—hence "field-programmable“FPGAs contain programmable logic components called "logic blocks", and a hierarchy of reconfigurable interconnects that allow the blocks to be "wired together"
