System-on-chip and data arbitration method thereof

摘要

A system-on-a-chip semiconductor device comprises a first master device configured to issue a request having a transaction ID, a plurality of slave devices configured to provide data in response to the request, and an interconnector configured to include a slave interface for providing the request to one or more master interfaces and for supplying response data to the first master device based on operation characteristics of the first master.;An arbitration method of an interconnector transferring a plurality of response data provided from a plurality of slave devices to a master device comprises selecting one of a plurality of arbitration modes based on operation characteristics of the master device; and transferring the response data in the order determined by transfer priority corresponding to the selected arbitration mode.

1. A system-on-a-chip semiconductor device comprising:
a first master configured to issue a request having a transaction ID; a plurality of slaves configured to provide data in response to the request; and an interconnector configured to include a slave interface and one or more master interfaces, the slave interface being configured to provide the request to the one or more master interfaces and supply response data to the first master based on operation characteristics of the first master, wherein the slave interface includes:
a reorder buffer configured to store the response data,a selector configured to selectively output the response data stored in the reorder buffer, anda control logic configured to control the output order of the response data according to a state of the reorder buffer.
