For these programming exercises, use only those instructions that have been discussed so far in these notes:

and

andi

nor

or

ori

sll

srl

xor

xori

1)

Put the following bit pattern into register $1 :

DEADBEEF 

A. Easy program: do this using just three instructions.

2) Start out a program with the instruction that puts a single one-bit into register one:

ori $1,$0,0x01 

Now, by using only shift instructions and register to register logic instructions, put the pattern 0xFFFFFFFF into register $1. Don't use another ori after the first. You will need to use more registers than $1. See how few instructions you can do this in. My program has 11 instructions.
