Abstract:
A bridge comprising:outbound pipe for buffering transaction information and data being transported from a plurality of devices to a bus;arbiter for granting requests associated with said devices to access the outbound pipe for transferring said transaction information and data into the pipe;means for generating a reject signal in response to an initial request associated with an initial transaction from a first one of said devices if the outbound pipe is unavailable to accept further transaction information or data;response control logic for generating a retry response for the initial transaction in response to the reject signal; andmeans for asserting a stamp signal in response to the reject signal,the arbiter in response to the stamp being asserted waits, without granting any other requests from devices having lower priority than the first device to access the outbound pipe, until a subsequent transaction from the first device makes progress, and wherein the reject signal is generated only if a first predetermined time has lapsed since the initial request.
