System architecture synthesis and exploration for multiple functional specifications
First Claim
1. A method for generating computer system level architectures that are capable of executing multiple functional specifications, given a set of physical resources, and subject to a set of design constraints, the method comprising:
- forming an initial master task graph from said multiple specifications, said initial master task graph including at least one hierarchical task having pointers to a plurality of sub-task graphs, wherein an XOR relationship exists between at least two of the plurality of sub-task graphs;
processing said initial master task graph to provide a selected number of final master task graphs, each of said final master task graphs comprising a list of AND task graphs;
generating a family of architectures for each of said final master task graphs, each of the architectures generated for a given final master task graph being capable of executing every AND task graph included in the list for the given final master task graph; and
exploring each of said generated architectures for use in executing said multiple specifications.

Abstract
A method is provided for exploring alternative architectures for partitioning computer system resources to execute multiple task specifications. An initial master task graph is formed from the multiple task specifications, the initial master task graph including at least one hierarchical task with pointers to either AND sub-task graphs or XOR sub-task graphs. The initial master task graph is processed to provide a selected number of final master task graphs, each of the final master task graphs comprising a list of AND task graphs. A family of architectures is generated for each of the final master task graphs, each of the architectures generated for a given master task graph being capable of executing every AND task graph included therein. The degree of resemblance in composition, functional capability or performance resulting between architectures from different master task graphs is a function of the correlation between the contents of these master task graphs and not of concern to the user of the aforementioned method.
