This document discusses the Raspberry Pi single board computer. It notes that the Raspberry Pi is developed by the Raspberry Pi Foundation in the UK and is credit card-sized. It uses a Broadcom BCM2835 system on a chip with a 700MHz processor and 256MB of RAM. The document discusses the Raspberry Pi's hardware components like its processor and RAM. It also discusses the Linux-based operating systems used like Debian and software drivers that interface with the GPU and APIs. It concludes the Raspberry Pi is lower priced than other computers, uses Linux, is smaller in size, and can display high quality video.

- 3. INTRODUCTION The Raspberry Pi is a credit card-sized single board computer developed in the United Kingdom (UK). Raspberry Pi is developed by Raspberry Pi Foundation. In 2014, the Raspberry Pi Foundation launched the Computer Module for use as a part of embedded systems to encourage their use. 3UNIVERSITY OF EDUCATION OKARA
- 4. The Raspberry Pi is based on the Broadcom BCM2835 system on a chip (SoC). SoC include an ARMII76JZF-S 700 MHz processor, Video Core IV GPU, and was originally shipped with 256 megabytes of RAM, later upgraded (Model B & Model B+) to 512 MB. The Foundation provides Debian and Arch Linux ARM distribution for download. 4UNIVERSITY OF EDUCATION OKARA
- 5. On the first 256 MB release model B (and Model A), three different splits were possible. As of October 2014, about 3.8 million boards had been sold. Structure of Raspberry Pi B+ shown below:- Raspberry Pi computer Model B+ 5UNIVERSITY OF EDUCATION OKARA
- 6. DISCUSSION Hardware Processor: • Level 2 cache is 128 KB, used primarily by the GPU, not the CPU. • The BroadCom SoCused in the Raspberry Pi is equivalent to a chip used in an old smart phones (Android or Apple). • A cluster of 64 Raspberry Pi Model-B computers, achieved a LINPACK HPL suite result of 1.14 GFLOPS (n=10240) at 216 watts for c. US$4,000. 6UNIVERSITY OF EDUCATION OKARA
- 7. RAM: 128 MB was allocated by default to the GPU, leaving 128 MB for the CPU. Raspberry Pi first time 256 MB release model B (and Model A), three different splits were possible. Default split was 192 MB (CPU RAM), which should be sufficient for standalone 1080p video decoding, or for simple 3D, but probably not for both together. 224 MB was for Linux only, with just a 1080p frame buffer, and was likely to fail for any video or 3D. 7UNIVERSITY OF EDUCATION OKARA
- 8. Software Operating systems: • The Raspberry Pi primarily uses Linux Kernel -based Operating Systems. • The install manager for the Raspberry Pi is NOOBS. The OSs included with NOOBS are: Archlinux ARM OpenELEC Raspbmc 8UNIVERSITY OF EDUCATION OKARA
- 9. Driver APIs: • Raspberry Pi can use a Video Core IV GPU via a binary blob, which is loaded into the GPU at boot time from the SD Card. • Video applications use Open Max, 3D use OpenGL Es. • 2D Application use Open VG which both in turn use EGL. • Scheme of the implemented APIs are given in next slide:- (conttd) 9UNIVERSITY OF EDUCATION OKARA

- 11. CONCLUSION Raspberry Pi is lowest price than other Computers. Raspberry Pi primarily uses Linux Kernel based Operating Systems. Raspberry Pi according to size is smaller than other computers as we compare. In October 2014 Raspberry Pi also improve the overall deficiency. Raspberry Pi also display high quality video (e.g 1080p). 11UNIVERSITY OF EDUCATION OKARA
