术语	I/O processor
释义	I/O processor 输入输出处理机;［输出入处理器］ The processor which executes its own programs to initialize, maintain, and perform diagnostics on all peripherals. It completely handles all “bookkeeping” and timing functions required by the peripherals, and communicates with the main CPU only when it has valid data to be examined or processed in conjunction with the execution of the main CPU program. The I/O processor will usually have its own RAM for buffer storage functions and, in order to enhance the I/O structure's realtime throughput, a simple access to DMA control functions is maintained. 执行自己的程序以实现对所有的外部设备的启动、维护和诊断的处理机。它处理所有的“管理操作”和外部设备所需的定时功能,当主CPU的程序涉及到要检查和处理有效的数据时,它与主CPU进行通信。输入输出处理机有它自己的RAM作缓冲存储器用。为了增强输入输出结构的实时吞吐量,它提供了简单的存取DMA控制功能。
