Abstract :
A behavioral model of a class of mixed hardware-software systems is presented. A codesign methodology for such systems is defined. The methodology includes hardware-software partitioning, behavioral synthesis, software compilation, and demonstration on a testbed consisting of a commercial central processing unit (CPU), field-programmable gate arrays, and programmable interconnections. Design examples that illustrate how certain characteristics of system behavior and constraints suggest hardware or software implementation are presented.<>
