在C語言中，可以用keep ( )函數將程序駐留內存。這個函數有兩個參數：status和size。size為駐留內存長度，可以用size=_SS+_SP/16-_psp得到，當然這也是一種估算的方法，并不是精確值。函數執行完以后，出口狀態信息保存在status中。比如，對于上面的例子，將“geninterrupt (0x60) ”改寫成“keep(0,_SS+_SP/16-_psp) ”后再執行程序，這一段程序就被駐留，此后在其它的任何軟件或程序設計中，只要用到了60H號中斷，就會在屏幕上顯示“This is an example!”的字樣。要恢復系統對60H號中斷的定義，只能重新啟動計算機。

ARM下 Implement matrix multiplication of 2 square matrices, with data read from an input file and printed both to the console and to an output file. • Assume a file with correct data (no garbage, characters, etc.). • you must check and provide appropriate execution for 2 extra cases, namely when the matrix size given is either “0” , or when the size is greater than the maximum handled of “5” . In these 2 cases you must implement the following behaviour: o If size = 0, then print a message “size = 0 is unacceptable” and continue by reading the next size for the next 2 matrices (if not end of file). o If size >5, then print two messages: “size is too big - unacceptable”. Then read and discard the next (size2 ) integers and continue by reading the next size for the next 2 matrices (if not end of file).

This book introduces embedded systems to C and C++ programmers. Topics include testing memory devices, writing and erasing Flash memory, verifying nonvolatile memory contents, controlling on-chip peripherals, device driver design and implementation, optimizing embedded code for size and speed, and making the most of C++ without a performance penalty.

This PNG Delphi version 1.56 documentation (this version is a major rewrite intended to replace the previous version, 1.2). Improvements in this new version includes: This new version allows the programmer to not use Delphi heavy units which will greatly reduce the size of the final executable. Read more about this feature here. Most, if not all, Portable Network Graphics features as CRC checking are now fully performed. Error on broken images are now better handled using new exception classes. The images may be saved using interlaced mode also. Transparency information won t be discarted after the image is loaded any more. Most of the images are decoded much faster now. The images will be better encoded using fresh new algorithms. IMPORTANT! Now transparency information is used to display images.

開發一個OS，盡管絕大部分代碼只需要用C/C++等高級語言就可以了，但至少和硬件相關部分的代碼需要使用匯編語言，另外，由于啟動部分的代碼有大小限制，使用精練的匯編可以縮小目標代碼的size
