HARDWARE SOFTWARE CO-DESIGN METHODOLOGY FOR DESIGN OF EMBEDDED SYSTEMS/

This paper presents the main co-design concepts of distributed embedde d hardware/software systems through a detailed presentation of a metho dology and an environment for codesign. This presentation gives a comp rehensive description of different codesign steps using a codesign of a realistic example: Real-Time Acquisition and Storage Controller acti ng between analog signals and storage disk. Design starts from a syste m-level specification and performs hardware/software partitioning, com munication synthesis and architecture generation. To produce an effici ent solution, the codesign process is guided by performance and constr aints that depend on the application context.
