how does cpu differentiate between 8bit and 16bit operations?

Answer 1

Don't listen to the other guy. He doesn't know what he's talking about.

The truth is 8-bit and 16-bit ops have different opcodes. Thus the CPU will know which part of the data register to use by the opcode used.

(see any Intel x86 assembly language guide and you'll see)

Answer 2

First of all CPU can't differentiate 8/16/ 32 / 64, it is the work of Memory controller and system bios that allows memory controller, memory and cpu registers to hold address of till these locations. CPU just have to process and request data from these location. it is handled by software also which sets the word size of 8/16 bits. Like TC or Turbo C++ which is 16bit program 'coz it is very old and prepared on 16bit computers, but runs on 32 bit that's why ur system goes to heat because of processor cycle increases to cover the loss of 16 bit.

Answer 3

i could say the two. i substitute into married for 11 years, and that i began out to sense unhappy, and then grew to alter into very depressed. It substitute into an exceedingly undesirable marriage. I did finally pass away.
