Due: Wednesday, February 4, 2009.
Distributed: Wednesday, January 28, 2009.
Reading Assignment:
- Katz/Borriello, Contemporary Logic Design 2e, Sections 4.2-4.3 (pages 164-205)
Exercises:
Please write legibly & show your work for full points.
- CLD2e page 214, Chapter 4, Exercise 4.7 parts a and b.
- CLD2e page 216, Chapter 4, Exercise 4.14 parts a and b. You may use inverted inputs.
- For the following problems, you may print the ROM, PLA and PAL worksheets or the worksheet which has all three on one page.
Implement the following three functions using a ROM, PLA and PAL.
For the PLA, try to minimize the number of AND gates you use.
- f1(a,b,c,d) = Σ m(8, 4, 12, 14, 13) + d(10, 6)
- f2(a,b,c,d) = Σ m(10, 12, 14) + d(6)
- f3(a,b,c,d) = Σ m(10, 4, 11, 13, 15) + d(9, 7)
Rationale:
- To practice implementing functions with multiplexers and decoders.
- To experience the design tradeoffs for PLAs, PALs, and ROMs.
