computer.
The CGM generates a base clock signal from which the system
clocks are derived. The CGM may include a crystal oscillator circuit
and/or phase-locked loop (PLL) circuit.
digital comparator defines the equality or relative differences
between two binary numbers.

contains the interrupt mask bit and five bits that indicate the results
of the instruction just executed.
the operation of the module.
contains logic functions that synchronize the machine and direct
various operations. The control unit decodes instructions and
generates the internal control signals that perform the requested
operations. The outputs of the control unit drive the execution unit,
which contains the arithmetic logic unit (ALU), CPU registers, and
bus interface.
