PROBLEMS HW#1 44, 5, 17 1. Explain each of the following terms in your own words: a. Translator. b. Interpreter. c. Virtual machine. 2. Is it conceivable for a compiler to generate output for the microarchitecture level in- stead of for the ISA level? Discuss the pros and cons of this proposal. 3. Can you imagine any multilevel computer in which the device level and digital logic levels were not the lowest levels? Explain. 4. Consider a multilevel computer in which all the levels are different. Each level has in- structions that are m times as powerful as those of the level below it; that is, one level r instruction can do the work of m level r- 1 instructions. If a level-1 program requires k seconds to run, how long would equivalent programs take at levels 2, 3, and 4, as- suming n level r instructions are required to interpret a singler + 1 instruction? 5. Some instructions at the operating system machine level are identical to ISA language instructions. These instructions are carried out directly by the microprogram or hard- ware rather than by the operating system. In light of your answer to the preceding problem, why do you think this is the case?. را
17. Developments in the computer industry are often cyclic. Originally, instruction sets were hardwired, then they were microprogrammed, then RISC machines came along and they were hardwired again. Originally, computing was centralized on large main- frame computers. List two developments that demonstrate the cyclic behavior here as well. 18. The legal issue of who invented the computer was settled in April 1973 by Judge Earl
