Cell Broadband Engine Architecture

• One general-purpose 64-bit processor, the Power Processing

Element (PPE).

• Eight simpler processors, the Synergistic Processing Elements

(SPE).

• A bus, the Element Interconnect Bus (EIB) that connects the

PPE and SPEs.

• PPE: PowerPC instruction set, 64 kB of L1 cache memory,

512 kB L2.

• SPEs: 128-bit registers (128), SIMD instructions than can

simultaneously process the four 32-bit words, 256 kB local store memory.

GNU/Linux

• An instalation of Linux to Playstation 3.
• The Linux distribution Fedora Core release 6 (Zod).
• Two Cell processors clocked 3192.0 MHz.
• Networking, it is posible to redirect X Window GUI:

ssh -X username@cortex2.felk.cvut.cz The option -X enables X Window forwarding.

• Standard unix libraries used for GUI operation (OpenGL,

SDL).

Intro GNU/Linux OpenGL SDL

OpenGL Utility Toolkit – GLUT

• a library of utilities for OpenGL programs, which primarily

perform system-level I/O with the host operating system.

• Functions for window definition, window control, and

monitoring of keyboard and mouse input.

• Routines for drawing a number of geometric primitives
• Include: GL/gl.h, GL/glu.h, GL/glut.h.
• Compilation:

gcc -lGL -lGLU -lglut -lm -o program source.c

• Documentation:

Intro GNU/Linux OpenGL SDL

Simple DirectMedia Layer

• A cross-platform multimedia library designed to provide low

level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL, and 2D video framebuffer.

• SDL supports Linux, Windows, Windows CE, BeOS, MacOS,

Mac OS X, FreeBSD, NetBSD, OpenBSD, BSD/OS, Solaris, IRIX, and QNX.

• SDL is distributed under GNU LGPL version 2.

SDL

PowerPC uses big endian byteorder! #if SDL_BYTEORDER == SDL_BIG_ENDIAN #define COLOR_BIT_MASK 0x000000ff, \ 0x0000ff00, \ 0x00ff0000, \ 0xff000000 #else #define COLOR_BIT_MASK 0xff000000, \ 0x00ff0000, \ 0x0000ff00, \ 0x000000ff #endif
