摘要: A method of automatically extracting information from an architecture description. A memory resident directed acyclic graph data structure comprising nodes representing instructions and edges whose weights represent dependencies between pairs of instructions is constructed. A list of ready nodes are maintained in the directed acyclic graph. A list of nodes not scheduled is maintained. And, it is determined whether the next instruction to be scheduled is to be taken from the list of ready nodes or from the list of nodes not yet scheduled.
