Computer Architecture: Decoder & Control Signal Encoder

Paper instructions:
I need to build a decoder and control signal encoder.

Decoder:

I need 1) the combinational logic equations, 2) the truth tables, and 3) the hardware logic circuit diagrams (using only AND, OR, NOT and other elemental logic devices as required) to automate these four functions for a motion control detector:

1) The camera will sweep the room (move side to side) while no motion is detected.
2) The camera will stop and focus/follow when motion is detected.
3) The record function will trigger when motion is detected.
4) Recorded video will store to SD card that is inserted when no more motion is detected.

Control Signal Encoder:
you really only need to have the Control Signal Encoder function developed for only 3 control signals: 1) Rout, 2) CONin and 3) Cout. The rest of the control signals have already been completed in the SRC design or are not needed in your design. Also, you only need to consider building an encoder to generate the control sequences for Three instructions above.
