Research output: Chapter in Book/Report/Conference proceedingConference contribution


This paper presents the development of parallel processing subsystems as part of multi-wavelength imaging pyrometers (M-WIPs) for real-time non-contact temperature measurement. The parallel processing subsystems are based on V-C40 Hydra or PC-Hydra which consists of four TMS320C40 floating-point digital signal processors. This paper describes the single- program-multiple-data implementation of the least-square fitting algorithm used in the M-WIP temperature measurement and compares its performance with the multi-program- multiple-data approach.
