- Assume we would like to extend the MIPS architecture to support
a larger register file with 256 registers and supporting twice as
many instructions.
- How would this architecture change affect the size of each of the bit fields in an R-type instruction?
- How would this affect the size of each of the bit fields in the I-type instruction?
- How could each of the two proposed changes decrease the size of a MIPS assembly program?
- How could each of the two proposed changes increase the size of a MIPS assembly program?

Write the program in MIPS
Initialize register $t0 (will hold the sum) to zero. Then add 409610 to $t0 sixteen times. You don't know how to loop yet, so do this by making 16 copies of the same instruction. The hexadecimal value of 409610 is 0x1000 Next, initialize register Stl to 409610. Shift St1 left by the correct number of positions so that registers $t0 and $tl contain the same bit pattern. Finally, initialize register $t2 to 409610. Add $t2...
