本文：采用了FPGA方法來模擬高動(dòng)態(tài)(Global Position System GPS)信號(hào)源中的C／A碼產(chǎn)生器。C／A碼在GPS中實(shí)現(xiàn)分址、衛(wèi)星信號(hào)粗捕和精碼(P碼)引導(dǎo)捕獲起著重要的作用，通過硬件描述語言VERILOG在ISE中實(shí)現(xiàn)電路生成，采用MODELSIM、SYNPLIFY工具分別進(jìn)行仿真和綜合。
What Does the code DO? Sometimes we may desire to hide our file contents from others.One of the possible way is encrypting these files.Here a simple encryption technique is used(In VB - The same technique can be implemented in "c" also.) Program flow Explained * Open the File to be encrypted for Binary Access Read(Say Source File) * Open a temparory file where encrypted data is stored for Binary Access Write(Say Destination File) * Loop through the Source File Byte by Byte * For each byte read from the file, Complement the data. (Using Not operator (in C we have to use "~" operator) * Write Complemented Data to Destination File * Delete the Source File * Rename Destination file as Source File(Now Encryption is over)
