    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.

    摘要: Generating a description of compiler code selector rules from an architecture description. A method comprises accessing a target architecture model written in an architecture description language (ADL) and extracting semantic information therefrom to generate a plurality of semantic statements. Rules that map from source code operations to semantic patterns are accessed. The semantic statements are searched for matches for the semantic patterns to generate mappings that serve as a description of compiler code selector rules.

    摘要: A method of simulating a program. Compiled and interpretive techniques are combined into a just-in-time cached compiled technique. When an instruction of a program simulation is to be executed at run-time, a table of compiled instructions is accessed to determine whether compiled data for the instruction is stored in the table. If the compiled data is not therein, the instruction is compiled and stored in the table. The compiled data is returned to a simulator that is executing the program simulation. In another embodiment, before storing new information in the table, another table may be consulted to determine if the location to which the new information is to be stored is protected. If the table location is protected, the new information is not stored in the table. Rather, the new information is simply passed on to the simulator.
