•Microprocessors are most commonly used as the CPU in microcomputer systems. Microcontrollers are used in small, minimumcomponent designs performing
•Microprocessor instruction sets are “processing intensive”, implying powerful addressing modes with instructions catering to large volumes of data. Their instructions operate on nibbles, bytes, etc. Microcontrollers have instruction sets catering to the control of inputs and outputs. Their instructions operate also on a single bit. E.g., a motor may be turned ON and OFF by a 1-bit output port.
