ABSTRACT:
An operating method applied to an out-of-order executive bus system includes: according to dependency constraints, linking requests using the bus system to form dependency request links having an order; and processing the order of the requests according to the dependency request links. In addition, a bus system is provided. The bus system includes a request queue and a dependency request link generator. The request queue receives and stores a newly received request including at least a link tag. The dependency request link generator generates N dependency request links according to dependency constraints of N link tags of the newly received request, where N is any positive integer. Each link tag of the newly received request is implemented to indicate a link relation with respect to an order of the newly received request and a plurality of unserved requests preceding the newly received request.
