Write a program that exchange a block of 128 bytes stored at locations starting at 34000h with another block starting at 36000h: • By using XCHG instruction • By using MOV instruction

For example, suppose an instruction is not accepted and VA page 30 is generated. For the following use cases, a TLB controlled by software might be preferable than one handled by hardware:

The "Add immediate unsigned" MIPS instruction: addi Rt, Rs, Imm requires the immediate field to be extended from 16 bits to 32 bits. If the value of the immediate field is: 1111000011110000 what will be the sign extended value of this field from 16 bits to 32 bits? Choose the best answer. 01111111111111111111000011110000 O 11111111111111111111000011110000 O This is a trick question. You cannot sign extend a negative number O 00000000000000001111000011110000 10000000000000001111000011110000 This is a trick question. You cannot sign extend a positive number
