1. SET BAUD RATE , PARITY , WORD SIZE , AND STOP BITS.

2. Currently, word size in general-purpose computers range from 8 to 64 bits.

3. While each of these is only a word size (4-byte) value, they are each aligned to 16 bytes for easy loading and storing (remember, the SPUs only load from 16-byte-aligned addresses).

4. A microprocessor's word size also applies to logic that handles data manipulations.

5. Here we discuss possible variations in the format of instructions, and the matching of instruction length to computer word size.

6. For example, an old person may want to enlarge the word size for his near-sighted eyes, or someone may want to zoom in the picture to watch its detail.

7. CPU speed is influenced by several factors, including clock rate, word size, cache and instruction set size.
