Exercises:
Familiarize yourself with the CSE
370 web pages. Make sure you have a CSE account and can login to the machines
in the instructional labs - especially in 003 (Baxter Lab). Subscribe to the course
mailing list so that you can access e-mail discussions among our community.
- The written assignments (such
as this one) account for what percentage of the final grade? How long
should you spend on each homework problem before discussing it with others?
What question would you like to see on the course evaluation that is
currently not on the list?
- Consider an encoding of a
chess board’s 64 squares that uses a minimum 6 bits – 3 bits
for the x position (x1, x2, and x3), 3 bits for the y position (y1, y2,
and y3). Derive a Boolean
expression that is true if a square is “black”. You can assume that 000, 000 is a
“black” square.
- There are 6 different types
of pieces on a chess board: king, queen, rook, bishop, knight, pawn. An encoding for the six requires a
minimum of 3 bits. Consider the
following encoding: the first bit is used to indicate whether the piece
can move only one square with a 1 or an arbitrary number of squares with a
0 (assume the pawn can only move forward 1 square for now, do not consider
other moves). The other two bits
are used to indicate whether the piece can move diagonally or orthogonally
to the axes of the board (you can assume the knight does not move either
diagonally or orthogonally and moves more than one square). Derive the encoding for the six pieces
using the following names for the 3 bits: “one”,
“diagonal”, and “orthogonal”. Do you have a unique encoding for each
of the six? Which encoding do you
not use? Describe the moves of the
“fictional” chess pieces for the encodings you are not using.
- CLD2e, 2.2, parts c, and e.
- CLD2e, 2.9.
- CLD2e, 2.12.
Rationale:
- To review number systems.
- To gain familiarity with some
of the basic concepts in digital logic.
