EDAC error detector and corrector have been implemented to improve the reliability of register file and memory during read and write process.

针对存储器和寄存器文件增加了EDAC检错纠错器对其读写过程进行检错和纠错。

Now using "zero copy" to improve this process: When the net card will catch the data packet later directly to write about the sharing memory, such treating processes reduced at least duplication.

利用“零存储”技术对传统的抓包过程进行改进：当网卡抓到数据包以后直接写到共享内存，这样的一个处理过程减少了至少一次复制。
