Abstract

Portable solid state audio players are currently reaching consumers through the advent of new audio compression algorithms and non-volatile flash memory technology. This paper presents a low-power, software programmable portable audio system utilizing these technologies. The key to this system is a 16-bit, fixed point digital signal processor (DSP) that handles decoding and other features while allowing software upgradeability.
