The BRISC: a high speed integrated processor dedicated to power control

Abstract

The authors present the BRISC (biprocessor reduced-instruction-set computer), an integrated digital processor designed for the control of two- or three-phase power systems through vector control, e.g. to implement field-oriented or predictive control for brushless or conductive motors. It is also able to perform pulsewidth modulation (PWM) on its own for inverter command. The BRISC executes a user-written program, and can be used in a large range of applications, whenever the control process is expressed in terms of plane vectors and/or when PWM is required. The BRISC integrates a high functionality and is fast enough to meet the requirements of the most demanding control schemes.<>
