What is word length of microprocessor?

Answer 1

Microprocessors have internal data pathways and internal registers with a fixed number of bits. An 32 bit processor will process 32 bit words, a 64 bit processor will process 64 bit words. The internal registers are sized to accommodate the word length with a single transfer. Generally, the more bits a processor can handle, the faster it can run. Smaller microprocessors might only process only 8 bits or less.

A word length is the data width that can be hold by the microprocessor. The word length is represented in bits.

word length is the instruction and other data handled by computers is in the forms of words.

a word is a group of bits.

Answer 2

It depends on the processor used and how the term is being used.
