AB  - The Motorola DSP56000 chip family is starting to appear in a number of digital musical and audio applications. Various claims have been made about the number of oscillators that can be implemented on the chip. Working within a prototypical hardware architecture that will be briefly discussed, I have implemented some table lookup oscillators in 56000 assembler. The oscillator can be used either as a sine-wave oscillator or for playback in a sampling synthesizer. The preprint for this paper includes code examples. In the preprint and in the oral presentation, the musical requirements for an oscillator will be presented, especially concerning updating the frequency and amplitude terms. There will be a discussion of the numbers of oscillators that can be achieved under varying conditions, and a discussion of possible software and hardware design tradeoffs.
