Control System Hardware Implementation - Microprocessors
• Microprocessors are generally low to high performance devices
that rely on external I/O peripherals and memory for proper
operation.
• Operational speeds are higher than microcontrollers.
• More complex instructions are available as well as some floating
point arithmetic on the chip or as a processor.
• can be used in low to moderate performance control systems,
including ancillary functions such as human-machine interfaces.
• Cost is moderate to high.
• Examples are Motorola’s 68000 and Power PC families; AMD
Opteron family, Cypress Semiconductor PSoC family and Intel
i960 family.
