介绍几种cpuThe 8xC251SA/SB/SP/SQ improves on the MCS-51 architecture and peripheral features, introducing the advanced register based CPU architecture i.e., the MCS 251 microcontroller architecture. The register based CPU supports a 40-byte register file. In addition, the 8xC251SA/SB/SP/SQ microcontroller has 256-Kbyte expanded external code/data memory space and 64-Kbyte stack space. The new controller is also specially designed to execute C code efficiently. More importantly, the 8xC251SA/SB/SP/SQ maintains binary code compatibility with MCS 51 microcontrollers but at the same time allows the use of the powerful MCS 251 microcontroller instruction set, with many new 8, 16 and 32 bit instructions available. The 8xC251SA/SB/SP/SQ has 512 bytes or 1 Kbyte of on-chip data RAM options and is available in 16 Kbytes and 8 Kbytes of on-chip ROM/OTPROM or ROMless options.

51上的RTOS，该RTOS为非占先式多任务操作系统，如果用户任务的最长执行时间小于 系统节拍时间，则本MiniRTOS要优于占先式TOS。因为本MiniRTOS占用资源小，RAM不超过20字节，程序空间只占为600多字节。

除了上面提到的压缩方法，你也可以调用VB的工具MakeCab.exe（在VB5\setupkit\kitfil32或VB98\Wizards\PDWizard目录下）生成.cab文件。先构造一个Directive 文件(*.ddf)，然后使用Shell命令调用MakeCAB /f excel.ddf就可以生成*.cab文件。关于Directive 文件的格式，可以参考MSDN Library中的《MakeCAB: A Compression and Disk Layout Tool》一文。

This program demonstrates how to do disconnected briefcase applications with ADO. When the Connected checkbox is unchecked the application is switched into offline mode. If the application is exited at that point then the data is persisted to a file on disk (along with any edits to the data). When the application is restarted it will load the persisted data if present, otherwise it will fetch the data from the database.

The flpydisk sample is a floppy driver that resides in the directory \\Ntddk\Src\Storage\Fdc\Flpydsk. It is similar to a class driver in that it sits a level above the floppy disk controller in the driver stack, and brokers communication between the application level and the low-level driver. The floppy driver takes commands from the application and then calls routines in the controller which will in turn perform the actual interaction with the device. The sample compiles in 64-bit, but has not been tested in this environment. It is compatible with x86 and Alpha platforms.

This version of the code is compatible only with the AT89C2051 due to the location of the data buffer and stack in RAM. The code may be modified to work with the AT89C1051 by relocating or resizing the buffer and stack to fit into the smaller amount of RAM available in the AT89C1051.
