Self-timed control circuit for self-resetting logic circuitry

A self-timed control circuit for self-resetting CMOS logic circuitry provides handshaking between macros to ensure that all data inputted to a particular macro is maintained by the source macros until all data inputs have been received. A data output signal from a macro is maintained until the macro receives a complete signal from all receiving macros indicating that the receiving macros have received all data inputs supplied to them.
