A high-speed programmable synchronous counter is disclosed. The high speed
counter includes a most-significant-bit counter synchronized with a
least-significant bit counter. The least-significant-bit counter is
programmed to an initial state and configured to decrement a state with
each pulse of a clock wave. The least-significant-bit counter provides an
output signal when the least-significant-bit counter has a zero-count
state. The most-significant-bit counter decrements when the
least-significant-bit counter has a zero-count state and provides an
output signal when the least-significant-bit counter has a zero-count
state. A counter output pulse is generated and the high-speed counter is
reset to the initial state when both the least-significant bit counter and
the most-significant bit counter have a zero-count state.
