1. A key factor in determining the cost of an integrated circuit is volume. Which of the following are reasons why a chip made in high volume should co st less? A. With high volumes, the manufacturing process can be tuned to a particular design, increasing the yield. B. It is less work to design a high-volume part than a low-volume part. C. The masks used to make the chip are expensive, so the cost per chip is lower for higher volumes. D. Engineering development costs are high and largely independent of volume; thus, the development cost per die is lower with high-volume parts. E. High-volume parts usually have smaller die sizes than low-volume parts and therefore have higher yield per wafer. The speed of the memory system affects the designer's decision on the size of the cache block. Which of the following cache designer guidelines are genera lly valid? A. The shorter the memory latency, the smaller the cache block B. The higher the memory bandwidth, the larger the cache block C. The shorter the memory latency, the larger the cache block D. The higher the memory bandwidth, the smaller the cache block Which of the following statements are generally true? A. Memory hierarchies take advantage of temporal locality. B. On a read, the value returned depends on which blocks are in the cache. C. Most of the cost of the memory hierarchy is at the highest level. D.Most of the capacity of the memory hierarchy is at the lowest level. 4. Which of the following statements about characters and strings in C and Java are true? A. A string in C takes about half the memory as the same string in Java. B. Strings are just an informal name for single-dimension arrays of characters in C and Java. C. Strings in C and Java use null ( 0 ) to mark the end of a string. D. Operations on strings, like length, are faster in C than in Java. 5.
