gdal是开发GIS 的重要库,可以操作栅格与矢量数据，这是最新的已编好的库，与visual 2005,2008 直接应用-gdal important is to develop GIS database, can operate grid and vector data, which is the latest has been a good library, with the direct application of visual 2005,2008

32×32的寄存器堆，它有32个32位的寄存器、两个读端口和一个写端口。该寄存器堆由3个层次共5个模块构成，最低层次的模块是D触发器，中间层次的模块包括32位寄存器、5位地址译码器、32选1多路选通器，顶层模块是寄存器堆模块。设计采用行为建模和结构建模相结合的方法，先用行为建模方法建立低层模块，然后再用结构建模方法搭建高层模块。-32 × 32 of the register file, it has 32 32-bit registers, two read ports and one write port. The register file by the three levels of a total of five modules, the lowest level module is the D flip-flop, middle-level module including 32-bit register, address decoder 5, 32 election more than one way strobe, and top-level module is Register File module. Design using behavioral modeling and structural modeling method of combining the first act of modeling methods used to establish low-level modules, then the structural modeling method to build high-level module.

基于MO保存GIS的另一个可视化工程文件(还是不够20个字)。已经说得很清楚了，为什么还要罗嗦呢?站长应该修改程序，免得让人罗嗦？-MO-based preservation of GIS visualization Another project file (20 words or less). Have explained very clearly, why this wordy? Regulators should revise procedures to prevent people wordy?
