Question

In a microprocessor, size of register  is generally:

1. Lesser than the size of the data it operates on
2. Greater than the size of the data it operates on
3. Equal to the size of the data it operates on

Comments

ANS: 3

 The processor takes operands from register itself if data bits are less then padding is used, and in one clock cycle, ALU cannot work with data of more than n bits.

Also, this shouldn't be asked in CN
