Marking of Final Exam

Question 1 (14 marks)

• 4 declaration input/output signals for each of two registers
• 3 test register input (for reset=1, high=1, high=0)
• 2 delta register input (for reset=1, reset=0)
• 2 process (syntax, if/else, assignments)
• 2 test_out, done signal assignments
• 1 syntax

Question 2 (14 marks)

• 2 save and restore registers
• 3 initialize, increment or decrement, conditional branch sample count
• 2 initialize, and increment pointer into buffer (may be combined with above)
• 2 output to LS bit of control register
• 3 input, AND mask and conditional branch on 'done' flag
• 2 input and store sample value

Question 3 (17 marks)

There were 2, 3, 2, 2, 3, 3, and 2 marks respectively awarded for the analysis of each of the 7 specifications (17 marks total). For each specification half a mark (3.5 of the 17 marks) was awarded for stating whether the specification was met or not based on the margin (regardless of whether the computed value was correct or not). If an incorrect equation was given no further marks were awarded for that specification. If the correct equation was given but the computed value or margin were numerically incorrect, one mark was deducted.

Question 4 (8 marks)

Two marks were awarded for the correct answer to parts (a) and (b) (no partial marks). One mark was awarded for each answer to the two questions in parts (c) and (d).

Question 5 (14 marks)

• (a) one mark for each correct answer (6 marks)
• (b) one-half mark for each correct answer (4 marks)
• (c) one mark for the each correct answer (2 marks)
• (d) one mark for each correct answer (2 marks)
