Time-sharing buffer access system

摘要

A time-sharing buffer access system manages a buffer among plural master devices. Plural buffer handling units are operable to associatively couple the master devices, respectively, and a first end of each buffer handling unit is used to independently transfer data to or from the associated master device. A second end of each buffer handling unit is coupled to a buffer switch. A time slot controller defines a time slot, during which one of the buffer handling units is selected by the buffer switch such that data are only transferred between the selected buffer handling unit and the buffer.

1. A time-sharing buffer access system for managing a buffer among a plurality of master devices, the system comprising:
a plurality of buffer handling units operable to associatively couple the master devices, respectively, a first end of each said buffer handling unit being used to transfer data to or from the associated master device independently of other master devices to simultaneously transfer data from all the master devices or to simultaneously transfer data to all the master devices; a buffer switch, to which a second end of each said buffer handling unit is coupled; and a time slot controller configured to define a time slot, during which one of the buffer handling units is selected by the buffer switch such that data are only transferred between the selected buffer handling unit and the buffer.
