Aiming at the characteristics and demands of working flow of Software Defined Radio(SDR) receiver, this paper develops a real-time data acquisition software. It works with intermediate frequency signal in Windows XP. Compared with single thread techniques, multi-thread can guarantee real-time performance and efficiency. The Event kernel object provided by operating system is used as the thread synchronization mechanism, so the interoperability between different threads is realized. Every thread has proper access to the same share resources. To some extent, the use of MFC makes codes reusable. The software is designed flexibly, and it is convenient and easy to maintain.
