术语 overlappedoperations buffer
释义 overlappedoperations buffer
重叠操作缓冲器;[交叠作业缓冲器]
Magnetic core buffers outside the main processor memory compensated for speed differences between slower electromechanical input/output devices and processor speeds. Operations are overlapped, with all units operating simultaneously at rated speeds. Buffering eliminates the need for more expensive, multiple I/O channels, and eliminates complex I/O timing considerations from the programming job.
主处理机存储器之外的一种磁芯缓冲器,用以平衡低速机电输入输出设备的速度与处理机速 度之间的差别。用缓冲器重叠操作时,所有单元同时以额定速率运行。缓冲作用不须要更昂 贵的多路输入输出通道,而且在程序设计中不要考虑复杂的输入输出定时问题。
