Chapter 4, Problem 19E

Shown below is a byte-addressible memory consisting of eight locations, and its associated MAR and MDR. Both MAR and MDR consist of flip-flops that are latched at the start of each clock cycle based on the values on their corresponding input lines. A memory read is initiated every cycle, and the data is available by the end of that cycle.

Chapter 4, Problem 19E, Shown below is a byte-addressible memory consisting of eight locations, and its associated MAR and , example  1

Just before the start of cycle 1, MAR contains 000, MDR contains 00010101, and the contents of each memory location is as shown.

Chapter 4, Problem 19E, Shown below is a byte-addressible memory consisting of eight locations, and its associated MAR and , example  2

a. What do MAR and MDR contain just before the end of cycle 1?

MAR: Chapter 4, Problem 19E, Shown below is a byte-addressible memory consisting of eight locations, and its associated MAR and , example  3 MDR: Chapter 4, Problem 19E, Shown below is a byte-addressible memory consisting of eight locations, and its associated MAR and , example  4

b. What does MDR contain just before the end of cycle 4?

MDR: Chapter 4, Problem 19E, Shown below is a byte-addressible memory consisting of eight locations, and its associated MAR and , example  5

Dijkstra's Algorithm (part 1).  Consider the network shown below, and Dijkstra’s link-state algorithm. Here, we are interested in computing the least cost path from node E (note: the start node here is E) to all other nodes using Dijkstra's algorithm. Using the algorithm statement used in the textbook and its visual representation, complete the "Step 0" row in the table below showing the link state algorithm’s execution by matching the table entries (i), (ii), (iii), and (iv) with their values.  Write down your final [correct] answer, as you‘ll need it for the next question.
