XScale cross-compilation environment setup and mplayer porting

Today, I got a botron pxa270a Development Board, but the random CD is down. The new CD should wait for at least next week, so I tried to build a cross-compilation environment. After searching for a day on Google, most of the Cross-compilation environment construction methods do not apply to this development board. Finally, finally found an open source project crosstool, using this tool can easily build XScale, ARM7-ARM9, mk6800, PowerPC and Other c

[Import] XScale, the "King" in memory "?

Unexpectedly, I really did not expect that Intel decided to sell "children" who have been raising for eight years so quickly. Some of them were born in Dec, and more of them are still under 8 years old. They are born in intel, and these children named "strongarm" or "XScale" are even more promising. They have arm genes in their bodies, but they are different from other similar genes with arm genes. Their core genes have been improved and designed, it

Hardware simulation implementation-Design and Implementation of SkyEye

according to the configuration file, simulate MMU/CACHE, and execute commands related to MMU/CACHE. If the CPU command simulation module executes the read/write memory operation command, it is transferred to the MMU/CACHE simulation module. If the simulated CPU type does not support MMU (such as arm7TDMI), SkyEye directly transfers the accessed address to the MEMORY simulation module or the I/O simulation module of the Development Board; otherwise, it is transferred to the simulation sub-module

Algorithm encapsulation of bilinear and bicubic

By chuckgao 2009 Recently, we have studied bilinear and bicubic algorithms for image scaling during video stream playback. Here is an algorithm that doubles the image in the latest project. For algorithm optimization, you can consider using the method of creating a scaling ing table. Bilinear algorithm: Int bilinear_scale(Long newx,Long newy,Unsigned long oldbytesperline,Unsigned long newbytesperline,Int format,Unsigned char * newimage,Image image){Unsigned char * PTR; If (newx = 0 | newy = 0 ){

For example, the map of Hainan has a large deformation, so we need to study how to eliminate the deformation.

we need to get the DPI of the display device, that is, the number of devices supported per inch. With the DPI we can switch between our accustomed units and unit units, using the API GetDeviceCaps (), which is powerful and can be referenced by MSDN, where we are only able to get the device dpi. Look at the sample code: [CPP] View plaincopy Some devices may be different in both horizontal and vertical dpi, so get them separately.

Animation style type One of the best tasks fusioncharts does is the graphic animation sequence, which is quietly enjoyed by users. By default, fusioncharts uses animations only when drawing data (such as a bar chart, pie chart, or line chart. However, fusioncharts V3 does not limit your imagination. With animation Styles, you can use animation effects for every object on the chart. You can customize an animation and apply it to various objects in the chart. Each chart object has an animati
