摘要： 为了提高双核处理器系统的性能，提出一种基于可扩展固件接口(EFI)、利用双核技术和IPI协议实现的协处理器模型。在EFI的DXE阶段，利用IPI协议引导启动一个与EFI系统并行的用户操作系统，将EFI系统作为一个后台服务系统(协处理器)处理用户系统的RPC请求。实验证明该分工协助的方式可以提高双核处理器系统的整体性能。

Abstract: In order to improve the performance of dual-core computer system, this paper proposes a coprocessor model based on Extensible Firmware Interface(EFI) and utilizes dual-core technology and InterProcessor Interrupts(IPI) protocol. In the Driver Execution Environment (DXE)stage of EFI boot process, a user operating system is booted through IPI protocol, and the EFI system runs as a background service system, acting as a coprocessor handling RPC requests from the user operating system. Experimental result proves that the performance of dual-core computer system is improved compared with the one only running the user operating system.
