Abstract
PURPOSE: To hold the response condition by receiving the access response from one and have a function to return the access response to the other as a joining device by joining two buses and receiving the access request from one and carrying out the access request.
CONSTITUTION: The access request receiving circuit 1 detects that the particular address range is made access by the bus 10, receives the access request and feeds the initiation command 101. The access request circuit 2 receives the initiation command 101 and feeds to the bus 20 the access request. the access response receiving circuit 3 receives the access response from the bus 20 or ehen receiving the unaccepted signal in the case of emitting the access request, the response signal 102 is emitted. The access response circuit 4 receives the response condition 102 and feeds the access response to the bus 10 and feeds the release signal 103 to release the busy condition of the access request acceptance circuit 1.
