- 1 - 1. (20 points) In this problem, you are to design a VHDL module called showHistory which uses the S3 board’s LCD display to show the most recent values from a sequence of input values. You should use the lcdDisplay module discussed in the notes as a sub-circuit of showHistory and you may borrow from the solution to Exercise 3 in the notes. Your circuit should have a four bit data input called dIn and a one bit signal called newValue . On any clock tick for which newValue is high, the value of dIn should be added to the sequence of values. displayed. Your circuit should display the most recent 16 values. The newest value should always appear in the leftmost position of the first line of the display. As new values are added, the older values should get shifted to the right, with blank spaces appearing to the right of the oldest value, when fewer than 16 values have been input. Your circuit should have a reset input and an output lcd of type lcdSigs . entity showHistory is port(
