    • A data transfer apparatus, system and method using the same are provided. A data transfer system according to an exemplary embodiment includes a user process space, a kernel space and a hardware space. A plurality of user processes are executed in the user process space. The kernel space includes a kernel thread. The hardware space performs an input/output according to the input/output request of the each user process. When input data based on the input request are received to the hardware space, the data transfer system checks whether the user process requesting the input is in an execution state, and allows the kernel thread to copy the input data from the kernel space to the user process space when the user process is in the execution state.
    • 提供了一种使用该数据传输装置的系统和方法。 根据示例性实施例的数据传输系统包括用户进程空间,内核空间和硬件空间。 在用户进程空间中执行多个用户进程。 内核空间包括一个内核线程。 硬件空间根据每个用户进程的输入/输出请求执行输入/输出。 当基于输入请求的输入数据被接收到硬件空间时,数据传输系统检查请求输入的用户进程是否处于执行状态,并允许内核线程将输入数据从内核空间复制到用户 用户进程处于执行状态时的进程空间。
