ABSTRACT:
A high performance, low cost microprocessor system having a variable speed system clock is disclosed herein. The microprocessor system includes an integrated circuit having a central processing unit and a ring oscillator variable speed system clock for clocking the microprocessor. The central processing unit and ring oscillator variable speed system clock each include a plurality of electronic devices of like type, which allows the central processing unit to operate at a variable processing frequency dependent upon a variable speed of the ring oscillator variable speed system clock. The microprocessor system may also include an input/output interface connected to exchange coupling control signals, address and data with the central processing unit. The input/output interface is independently clocked by a second clock connected thereto.
