Conference Paper

Using Multiple Processors for Real-Time Audio Effects

Authors: Bogdanowicz, Ken; Belcher, Robert

AES Conference: 7th International Conference: Audio in Digital Times · Paper 7-047 · May 1989

Abstract

This paper will try to provide insight into a realworld application of multi-processing, where -parts' cost- is a never-ending concern. In particular, we will describe the hardware and software issues involved in the design of Eventide's H3000 Ultra-Harmonizer, a general-purpose audio effects processor. The processor uses a computing architecture based on multiple TMS32010 digital signal processing chips and an 8 bit host microprocessor. We will show how our design addressed the problems of processor synchronization, host processor interfacing, and the division of software tasks amongst the processors. To illustrate these issues, we will discuss the implementation of some of our audio effects programs.
