5-27. In terms of access and capacity of a cache memory, a cache memory is usually on the order of one magnitude (a) (slower; faster) than main memory and its capacity is two orders of magnitude (b) than main memory. (less; more) 1.   (a)   Slower   (b)   less 2.   (a)   Slower   (b)   more 3.   (a)   Faster   (b)   less 4.   (a)   Faster   (b)   more 5-28. Which of the following methods can be used by a cache memory to indicate which entries of main memory have been copied into  it? 1.  A  hit 2.  A  tag  store 3.  An  identifier 4.  Both  2  and  3  above 5-29. Which of the following is/are properties of cache memory? 1.   A   high-speed   memory 2.  A  logical  network  and  an  old  entries replacement   method 3.   Timing   and   control 4.  Each  of  the  above 5-30. To indicate that data from the requested address is present, which, if any, of the following terms is used? 1. 2. 3. 4. Hit Miss Tag None of the above 5-31. What area of cache memory writes only to the directories? 1.   Updates 2.   Invalidates 3.   Searches 4. Tags 5-32. What cache process is performed by a requestor other than the CPU within? 1 .    M a i n 2.   Mapping 3.   Eavesdrop 4.   Searching IN ANSWERING QUESTIONS 5-33 THROUGH 5-36, SELECT FROM THE FOLLOWING LIST THE CACHE MAPPING TECHNIQUE DESCRIBED IN EACH QUESTION. 5-33. 5-34. 5-35. 5-36. 5-37. 1.   Direct   mapping 2.   Fully   associative   mapping 3.   Set   associative   mapping Is the most flexible cache mapping technique with regards to where data can reside. Combines the best cache mapping techniques. Main memory locations can only be copied into  one  location  in  cache. If cache is fill, a replacement algorithm is used to decide which block gets replaced by  new  data. What cache read method can be used to present the cache and main memory with the reference simultaneously? 1.   Look-aside,   serial   read 2.   Look-aside,   parallel   read 3.   Look-through,   serial   read 4.   Look-through,   parallel   read 37
