BUS ARBITER AND METHOD FOR ACCESSING ASYNCHRONOUS TRANSFER MODE INTERCONNECTION BUS

摘要

1. TECHNICAL FIELD OF THE INVENTION;The present invention relates to a bus arbitration apparatus and method for mediating the connection of an ATM interconnect bus.;2. The technical gist of the invention to solve;SUMMARY OF THE INVENTION An object of the present invention is to provide a bus arbitration apparatus and method that can overcome the bottleneck of system input / output performance in supporting various multimedia application services by adopting a self-priority determination method in an ATM interconnect bus.;3. Summary of the Solution of the Invention;The present invention provides a frame pulse generating means for outputting an internal bus frame clock; Selection means for selectively outputting an external bus frame clock and the internal bus frame clock; And bus arbitration means for determining an asynchronous delivery mode interconnect bus interface to be authorized for bus access.;4. Important uses of the invention;The present invention is used to arbitrate a bus connection in an ATM interconnect bus, which is an I / O bus in asynchronous delivery mode.
