Quantum CPU Modules
Overview The Quantum CPU is a module residing on the Quantum local I/O backplane. The
CPU is a digitally operating electronic system, which uses a programmable memory
for the internal storage of user instructions. These instructions are used to
implement specific functions such as:
z Logic
z Process sequencing
z Timing
z Coupling
z Arithmetic
These instructions allow control through digital and analog outputs, for various types
of machines and processes.
The Quantum CPU serves as a bus master controlling the local, remote, and
