In-Depth Information
a) Implement this machine using the pointer-based technique and VHDL or System-
Verilog. Start by making the proper adaptations (using pointer(s)) in the state transi-
tion diagram. Create an array of constants to be placed at the output in states B and
F, and chose numeric values for
y
A
,
y
C
,
y
D
, etc.
b) Show simulation results. To ease the inspection of the results, use 3 instead of 8
and 2 instead of 7 in the repetitions.
Exercise 15.4: Clock with LCD Display
Redo the design of section 14.1.3 using the pointer-based technique. Start by drawing
the adapted (using pointer(s)) state transition diagram. After compilation, compare
the resources usage (especially the number of l ip-l ops) against the results obtained
after compiling the code of section 14.1.3.
Exercise 15.5: I
2
C Interface for an RTC
Redo the design of section 14.2.5 using the pointer-based technique. Start by drawing
the adapted (using pointer(s)) state transition diagram. After compilation, compare
the resources usage (especially the number of l ip-l ops) against the results obtained
after compiling the code of section 14.2.5.
