实际上，内核本身的大部分都驻留在虚拟内存中，这样可以帮助释放内存段以供其他进程使用。

In fact, most of the kernel itself resides in virtual memory, which helps free up segments for other processes.

例如，假定一个虚拟处理器持有一个锁，并且它没有足够的周期来释放这个锁。

For example, assume one virtual processor is holding a lock and does not have enough cycles to release that lock.

随后，可将该应用程序的各部分迁移到FPGA中的虚拟“硬件”，从而释放CPU资源供其他任务使用。

Later, you can migrate various parts of the application into virtual "hardware" inside the FPGA, thereby freeing up CPU resources for other tasks.
