18. How many fields does an I-type of instruction have? 5 point 3 4 5 06 19. Since. In the 32-bit MIPS, only 6 bits are used to code the operation there is no more potential for MIPs to grow its capability unless it dramatically increases to 64-bit ISA Sports a true b. false 20. add $81, $2. $3 is no R-type instructions OOC type of instruction J-type of instruction 14. The number of registers in a processor is quite small (only 32 in MIPS) 5 points probably because a. The registers are too expensive to make O b. If the number is too big, the system clock's frequency would be reduced 15. Using the simple math rule that the y is said to be the negatite of 1 theny - 1 = 0 to figure out the 32-bit pattern for representing -1. It is 5 point - Your answer 16. What is the l's complement of 32-bit bf 1? point Your answer 17. In MIPS, a word has bytes pointa #1 b.2 Od 11. Theoretically, a 32-bit machine can have 4 billion different instructions. 5 points The closest estimate about the number of distinct instructions a 64-bit machine can have is O . 2*4 billion = 8 billion b. 64 billion O c. 3232 billion Od 16 billion of billion 12. Suppose that a, b, care variables, le, memorial locations, the translation of C/C++/java code: ca+b; into MIPS assemble instructions will need s points O a. At least two registers and two lines of assemble instructions O b. At least two registers and three lines of assemble instructions c. At least three registers and two lines of assemble instructions d. At least three registers and three lines of assemble Instructions 13. Which of the following lines of codes is valid in MIPS? alw $t0, 6(S13) Spoints b. lw $10,7513 c. lw t0,($13) d lw $10.94513)
