datenpufferspeicher type first - in first - out with a variable and fixed exit entrance

摘要

A data buffer memory for the first-in, first-out type, having an input bus by which data are supplied to the buffer, and a fixed output from which data are transferred from the buffer. Each section of the buffer includes logic whereby a variable input location can be selected. Status signals are used to determine, in cooperation with signals supplied from outside the buffer, the location where data are to be written in the buffer and when these data in the buffer must be shifted to the output.
