etc

4. Why you should use one
o Low cost and low power
● Simple to use
● Educational device for youths
● Versatile for many different projects/applications
● Compact Size

5. MOTIVATION
 Computer science skills are important. Computers are the tool of
the 21st century
 Computer Science is concerned with much more than simply being
able to use a computer.
 For Developing CS skills. Easy access to computers
 One should understand how they work and how to program them,
easily and affectively.

6. FEATURES
 Provide a fun environment for experimenting with programming and
electronics.
 Inexpensive, simple, open and easy to maintain , Ultra low-cost
(Model A $25, Model B $35).
 Complete easy-to-program computer.

7. TECNOLOGY
 The Raspberry Pi has a Broadcom BCM2835 system on a chip ,
which includes an ARM1176JZF-S 700 MHz processor .
 It does not include a built-in hard disk , but uses an SD card for
booting and long-term storage.
 Dual Video Core IV GPU, Video Core IV GPU
 First model had 256MB RAM, newest has 1GB,2GB.

8. HARDWARE
4 Models: A, A+, B, B+.
● ARM1176JZF-S Processor
o Typical clock size is 700 MHz, preforming at approximately 40
MFLOPS, Can be overclocked to 1GHz without any issues.
● Includes Video Core IV graphics processor with1 billion pixels per
second.
● 512 MB of RAM is built into the board, not replaceable or
upgradeable
● Includes multiple built on I/O ports
o 100 MB/s Ethernet port
o HDMI port and RCA port
o Audio Jack

9. RISC Architecture
 Low Transistor Count
● Low Power Consumption/Heat Production
● Used in most mobile devices
o Phones
o Laptops
o Small Digital Devices

Raspberry Pi has similar requirements to
mobile devices

Architecture allows for various Unix Os, Raspberry Pi can utilizes
nearly all
Linux.

10. Instruction Set
 3 Instruction Sets
32 Bit ARM
Single Instructions
Handles Data
Organizes Processor Segments

16 Bit Thumb
Specialize in branch range and address space
Used with ARM for rapid interrupts
Used for Digital Signal Processing

8 Bit Java
Jazelle Technology
Deals with complex Java bytecodes

11. Pipelining
 8 stage pipeline
Data path consists of three pipelines:
ALU, shift,
Load or store pipeline
 Fetch stages can hold up to four instructions. Branch prediction
performed on instructions ahead of execution of earlier instructions
 Issue and Decode stages can contain any instruction in parallel with
a
predicted branch
 Execute, Memory, and Write stages can contain a predicted branch,
an
ALU, or multiply instruction load/store multiple instruction, and a
coprocessor instruction in parallel execution.

12. OPERATING SYSTEM
 Raspbian
 Fedora
 Arch-Linux ARM
 Windows 10 On Raspberry Pi2 (up-coming)

13. Programming on a Pi
 By default, It supports Python as the educational language.
 Any language which will compile for ARM v6 can be used with
the Raspberry Pi
 Raspberry Pi supports multiple Linux distributions
Ubuntu
Openelec
OSMC
 The installed ARMv6 also handle many languages
Python
C
C++
Java
Ruby
Scratch
 More programming languages can be installed with proper
support tools

14. Applications
 While originally used to teach kids about programming, the
Raspberry Pi
has evolved to be used for a multitude of different applications
 Automated Light Control System
 Game System Emulator
 Surveillance System
 Universal Remote Control system
 Automated House system
 Music Streaming Speakers , and a-lot more…,
