Method and system for synchronous handshake generation

A method for providing synchronized handshake between a request signal initiating station and a responding station of a digital system, said stations operatiing from a common clock, comprising the steps of:

• transmitting a first request signal from said initiating station at the occurence of a first clock pulse of said common clock;
• receiving said first request signal by said responding station, detecting a ready status of a ready-to-acknowledge control signal, and transmitting an acknowledge signal to said initiating station at the occurence of a second clock pulse of said common clock;
• receiving said acknowledge signal at said initiating station, detecting a ready status of a ready-to-request control signal, and transmitting a consecutive second request signal from said initiating station at the occurrence of a third clock pulse of said common clock;
• and
• wherein said first and second request signal and said acknowledge signal have a duration of more than one clock cycle and less than two clock cycles and wherein said first, second and third clock pulse are consecutive clock pulses of said common clock.

An apparatus for providing synchronized handshake between a request signal initiating station and a responding station of a digital system, said stations operating from a common clock, comprising:

• first means coupled to transmit a first request signla from said initiating station at the occurence of a first clock pulse of said common clock;
• second means coupled to receive said first request signal at said responding station, to detect a status of a ready-to-acknowledge control signal, and transmit an acknowledge signal to said initiating station at the occurrrence of a second clock pulse of said common clock and in response to a ready status of said read-to-acknowledge control signal;
• said first means coupled to receive said acknowlege signal and transmit a consecutive second request signal at the occurence of a third clock pulse of said common clock;
• and
• wherein said first and second request signal and said acknowlege signal have a duration of more than one clock cycle and less than two clock cycles and wherein said first, second and third clock pulses are consecutive clock pulses of said common clock.

A method for providing synchronized handshake between a request signal initiating station and a responding station of a digital system, said stations operating from a common clock, comprising the steps of:

• transmitting a first request signal from said initiating station at the occurrence of a first clock pulse of said common clock;
• receiving said first request signal by said responding station;
• detecting a not-ready status of a ready-to-acknowledge control signal, and in response thereto introducing a wait period at said responding station for delaying transmission of an acknowledge signal to said initiating station;
• detecting a ready state of said ready-to-acknowledge control signal and transmitting an acknowledge signal to said initiating station at the occurrence of a second clock pulse of said common clock;
• receiving said acknowledge signal at said initiating station and transmitting a consecutive second request signal from said initiating station at the occurrence of a third clock pulse of said common clock;
• and
• wherein said first and second request signal and said acknowledge signal have a duration of more than one clock cycle and less than two clock cycles and wherein said first, second and third clock pulse are non-conseutive clock pulses of said common clock.
