What is oil buffer?

Also known as oil buffer, it points to two kinds of input buffers and output buffers. The role of the former is sent to the peripheral data is temporarily stored,So that the processor will take it away; the latter role is used to temporarily store data processor sent to the peripherals. With NC buffer, feed controller can make high-speed CPU peripherals and slow work of coordinating and working buffer to achieve synchronous data transfer. Since the buffer connected to the data bus, it will have a tri-state output. Another buffer elevator, car spring buffer.
