Euphony Logos

c. 1996

The Euphony chip is a low cost RISC processor with DSP functions and ATM interface.  Euphony was developed by the Research Initiatives Laboratory (Lab 1128) of AT&T Labs Research as a low cost AAC/PAC decoder and for experiments in digital audio and home networking.  Euphony samples were available to anyone in AT&T in 1996.

Euphony is an inexpensive, low power, high performance embedded processor for signal processing and networking. It consists of a MIPS II compatible RISC processor that has been augmented with a fast pipelined multiplier and signal processing instructions. Eu\phony contains most of the logic on chip required to build a complete system. It contains all of the logic necessary to provide a near "glueless" interface to standard SRAMs, DRAMs, VRAMs, and many peripheral devices.  For systems requiring only a small amount of memory, the internal instruction a\nd data caches can be used as local
memory. Power on reset generation, a crystal oscillator, a counter-timer, an interrupt handler, and a DMA controller are provided internal to the chip.  Euphony provides 16 general purpose I/O pins. These application specific I/O pins may be configured in numerous ways to provide flexible input and output functions with a minimum of external circuitry. A serial interface that can interface to many popular DACs, ADCs, and codecs is provided.  Finally, an ATM interface that implements both the UTOPIA and AT&T DPI protocols is provided for connection to ATM networks.

The following are some of my logo designs for euphony.  Click on an image for a larger version.
Euphony logo - euphony chip
This design clearly incorporates the major elements: the euphony name, music, and the chip.
Euphony logo - e note chip
This design has been simplified too far, the euphony name has been lost.
Euphony logo - orca
This design has lost the chip element - a chip background could be added, but it makes the orca less striking.  The orca retains the audio/sound/music element, and the killer whale leads to killer apps and killer chips, we hope.  The placement of the 'p' and 'h' worked out perfectly.  The design was fun to develop and it brought back fond memories of the Pacific Northwest.
