MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -Bandwidth − It is the number of bits processed in a single instruction. Clock Speed − It determines the number of operations per second the processor can perform. It is expressed in megahertz (MHz) or gigahertz (GHz).It is also known as Clock Rate.

Detailed explanation-2: -"Word size” refers to the number of bits processed by a computer’s CPU in one go (these days, typically 32 bits or 64 bits). Data bus size, instruction size, address size are usually multiples of the word size.

Detailed explanation-3: -At a time, an 8-bit CPU can process 8 bits of data. Depending on the type of microcomputer, the word length might range from 4 to 64 bits. The largest amount of data that a processor’s accumulator/working register can handle at a given time instant is the data bus width.

Detailed explanation-4: -The number of bits processed at one time is the processor’s register size (word size). Intel’s 8086 processor’s register size is 16 bits, or 2 bytes. Today’s CPUs have register sizes of 64 or 128 bits.
