(Practice) a. Using Figure 2.14 and assuming the variable name rate is assigned to the byte at memory address 159, determine the addresses corresponding to each variable declared in the following statements. Also, fill in the correct number of bytes with the initialization data included in the declaration statements. (Use letters for the characters, not the computer codes that would actually be stored.) floatrate; charch1=M,ch2=E,ch3=L,ch4=T; doubletaxes; intnum,count=0; b. Repeat Exercise 9a, but substitute the actual byte patterns that a computer using the ASCII code would use to store characters in the variables ch1, ch2, ch3, and ch4. (Hint: Use Appendix B.)

Suppose you executed the code below on a version of the pipeline from COD Section 4.5 (An overview of pipelining) that does not handle data hazards (i.e., the programmer is responsible for addressing data hazards by inserting NOP instructions where necessary).

In this case, there will be a structural hazard every time a program needs to fetch an instruction during the same cycle in which another instruction accesses data. 4.22.1 [5] <§4.5> Draw a pipeline diagram to show were the code above will stall. 4.22.2 [5] <§4.5> In general, is it possible to reduce the number of stalls/NOPs resulting from this structural hazard by reordering code? 4.22.3 [5] <§4.5> Must this structural hazard be handled in hardware? We have seen that data hazards can be eliminated by adding NOPs to the code. Can you do the same with this structural hazard? If so, explain how.

Below is a list of 32-bit hexadecimal memory addresses, given as byte addresses. 74, A0, 78, 38C, AC, 84, 88, 8C, 7C, 34, 38, 13C, 388, 18C For each of these references, identify the index and the tag, given a three-way set associative cache with two word blocks and a total of 24 words. List if each reference is a hit or a miss, assuming the cache is initially empty and show every entry to the cache, including the tag value and the addresses of all data items stored. Use hexadecimal or binary, whichever is easier.
