7 – Sequential Logic Examples
Digital combination lock (new data-path to decrease number of inputs)
Remove 3 code digits as inputs
- use code registers
- make them loadable from value
- need 3 load signal inputs (net gain in input (4*3)–3=9)
- could be done with 2 signals and decoder (ld1, ld2, ld3, load none)
