中文摘要:

      针对数据采集系统对实时性要求高的特点，充分发挥多核处理器的优点，利用处理器关联操作修改计算机中所有进程的处理器关联，让实时性要求高的线程独占一个处理器做到“专核专用”。测试证明运用该方法后性能得到了提升，并且不受其他进程和处理器运行状况的影响，最终将该方法运用到一个数据采集系统中，取得了良好的效果。

英文摘要:

      According to demand of high real-time for data acquisition system,the advantages of multi-core are fully taken by using processor affinity technology and binding the thread,which has demand of high real-time with a processor.Testing proves that performance is improved and don’t get influence from processor operating conditions.Finally,this method is applied in a data acquisition system and get a very good effect.
