DATA INTERFACE REGISTER STRUCTURE WITH REGISTERS FOR DATA, VALIDITY, GROUP MEMBERSHIP INDICATOR, AND READY TO ACCEPT NEXT MEMBER SIGNAL

Embodiments of the invention include a system for an integrated circuit development. Elements of the development system include hardware and software objects. Boundaries of the objects may include register structures, which regulate data transfer between and within objects. Protocols, including forward and reverse protocols indicate when data is ready to be accepted, and when it is valid and ready for use. Further, specific protocol information indicates the beginning and end of a group of data. Specialized objects include fork and join objects. Fork objects have more register structures for output than they do for input, while join objects have fewer register structures for output than they do for input.
