Abstract
An integrated circuit which contains an on-chip clock that operates the integrated circuit at its true maximum speed is disclosed. The integrated circuit operates asynchronously from a processor bus and contains circuitry for interfacing with the processor bus. A clock generator is constructed using information obtained from identifying a slowest signal path of the integrated circuit. The clock may be stopped and started under processor control to permit communication between the IC and processor bus.
