Please help with these questions:

1- Name all 32 bit registers inside 80x86 microprocessor.

2- Name all 16 bit registers inside 80x86 microprocessor.

3- Name all 8 bit registers inside 80x86 microprocessor.

4- Which of the following instructions are invalid? Discuss why they are invalid? If the instruction is valid, state what does happen after it is executed. Lets assume EAX has the value 0x000020F0 (hex 000020F0 0010 0000 1111 000). Also memory locations $20F0, $20F1, $20F2 and $20F3 have the values 1, 2, 3 and 4.

a) MOVB %AL, %BL

b) MOVL 0x300, %EBX

c) MOVW %ECX, 0x30

d) MOVB 0x3400, %AL

e) MOVW %AX, %AL
