Ethical and Environmental Analysis Audio Lossless compression in an FPGA (ALF) Team 6 Ken Pesyna David Eslinger AJ Hartnett Curt Schieler

ALF ALF = Audio compression Losslessly on an FPGA Implements FLAC audio compression (which includes Rice Encoding) on an FPGA Recording, Compression, Decompression, and Playback capabilities

IEEE Code of Ethics “to accept responsibility in making decisions consistent with the safety, health and welfare of the public, and to disclose promptly factors that might endanger the public or the environment”

Manufacturing Stage Environmental Impact – Airborne particulates, waste rinsewater – Waste streams: copper, lead, arsenic, etc. How to address – Design the board to be compact – Use RoHS-compliant parts

“Normal Use” Stage Environmental Impact – Power consumption How to address – Design a more power-efficient circuit – Provide recommendation in user manual to turn device off when not in use

Deathbed Stage Challenges – Proper disposal – User awareness of proper disposal method How to address – Include information about PCB and LCD recycling channels in user manual – PCB recycling: recover lead, tin, nickel, copper – LCD recycling: incinerate to form glass substrates
