Timing generator for a pixel-based display. The timing generator is intended for display processors driving a standard rasterized display. The simplest possible display processor needs to derive from this class and override the nextPixel() method to feed the display with pixel data. Pixels are ordered relative to the top left corner of the display. Scan lines appear in the following order: * Vertical Sync (starting at line 0) * Vertical back porch * Visible lines * Vertical front porch Pixel order within a scan line: * Horizontal Sync * Horizontal Back Porch * Visible pixels * Horizontal Front Porch All events in the timing generator are automatically suspended on a drain() request and restarted on drainResume(). This is conceptually equivalent to clock gating when the pixel clock while the system is draining. By gating the pixel clock, we prevent display controllers from disturbing a memory system that is about to drain.
This is the gem5 simulator. The main website can be found at http://www.gem5.org A good starting point is http://www.gem5.org/Introduction, and for more information about building the simulator and getting started please see http://www.gem5.org/Documentation and http://www.gem5.org/Tutorials. To build gem5, you will need the following software: g++ or clang, Python (gem5 links in the Python interpreter), SCons, SWIG, zlib, m4, and lastly protobuf if you want trace capture and playback support. Please see http://www.gem5.org/Dependencies for more details concerning the minimum versions of the aforementioned tools. Once you have all dependencies resolved, type 'scons build/<ARCH>/gem5.opt' where ARCH is one of ALPHA, ARM, NULL, MIPS, POWER, SPARC, or X86. This will build an optimized version of the gem5 binary (gem5.opt) for the the specified architecture. See http://www.gem5.org/Build_System for more details and options. With the simulator built, have a look at http://www.gem5.org/Running_gem5 for more information on how to use gem5. The basic source release includes these subdirectories: - configs: example simulation configuration scripts - ext: less-common external packages needed to build gem5 - src: source code of the gem5 simulator - system: source for some optional system software for simulated systems - tests: regression tests - util: useful utility programs and files To run full-system simulations, you will need compiled system firmware (console and PALcode for Alpha), kernel binaries and one or more disk images. Please see the gem5 download page for these items at http://www.gem5.org/Download If you have questions, please send mail to gem5-users@gem5.org Enjoy using gem5 and please share your modifications and extensions.
