Title:
BURST MODE DATA BLOCK TRANSFER SYSTEM
Document Type and Number:
Japanese Patent JPS59167767
Kind Code:
A
Abstract:
A data transfer system whereby a peripheral-controller manages data transfers between a host computer and a magnetic tape peripheral unit. The peripheral-controller provides a buffer memory for data being transferred. Data residing in the buffer memory is monitored by a block counter monitoring system which informs a program- sequencer in the common control circuit unit (of the peripheral-controller) when it may branch to routines permitting blocks (256 words) of data to be "shifted into" or "shifted out of" the buffer memory. This is done in a "burst mode" operation where entire blocks of 256 words are shifted from the host computer 10 to the buffer 22 (write direction at 64 megabits per sec.) or shifted from the buffer 22 to the host 10 (read direction).
