可重构系统中基于MMU的<br /> 软硬件任务间通信方法的研究<br />
Journal Title: Science Paper Online - Year 2010, Vol 5, Issue 1
Abstract
由现场可编程门阵列(FPGA)和CPU构成的动态可重构混合系统具有计算性能高、灵活性强、适用范围广等优点，它的出现使硬件与软件的界限变得模糊，让软件拥有了硬件的高性能，硬件具备了软件的灵活性。但是由于硬件任务不支持程序上下文切换，不具有虚拟内存机制，不能够唤醒系统服务，混合软硬件任务的运行使得程序的虚拟和系统软件的可迁移性降低。提出了一种基于存储管理单元(MMU)的软硬件任务间通信方法，通过引入一种基于MMU思想的虚拟地址映射机制，在硬件中实现了描述MMU进行虚拟地址映射行为的模块，使硬件任务同软件任务一样具有虚拟地址，并利用这种机制实现了软硬件任务之间的通信。
