Due: 11/5/03 (wed)

Turn these in by hand at the beginning of class.

Textbook problems (2 pts per problem)

• Textbook Problem 5.1.  Note that the processor in Figure 5.19 can only execute the following instructions:  R-type (arithmetic), lw, sw, and beq.  You must consider each of the four possible stuck-at-1 fault (RegstDst=0, ALUSrc=0, MemtoReg=0, and Zero=0) separately, and for each fault, list the instructions that still work.  
• Textbook Problem 5.6.  Similar to Problem 5.5 that was in Homework 8.
• Textbook Problem 5.15.  This is for the multicycle MIPS.  
• Textbook Problem 5.16.  Microcoding exercise.
