In this paper we describe a digital signal processor using TMS320C40 for image recovery applications. The ability for large-size 2-D FFT is a key consideration in the design. By using the vector radix technique, the FFT of size 256 256 may be executed in 190ms by utilizing two C40 chips. A software simulation has been done to verify the design.Übersicht: In der vorliegenden Arbeit wird ein auf TMS320C40-Chips basierender Signalprozessor für Anwendungen zur Bildwiederherstellung beschrieben. Die Fähigkeit zur Bewältigung der zweidimensionalen schnellen Fourier-Transformation (FFT) auch im Fall großer Datensätze bildet den Entwurfsschlüssel. Unter Verwendung der Vektor-Radix-Technik läßt sich die FFT von der Größe 256 256 in 190 ms mit Hilfe von zwei C40-Chips durchführen. Zur Verifikation des Entwurfs wurde eine Computersimulation durchgeführt.Für die Dokumentation: Digitaler Signalprozessor / Bildwiederherstellung / TMS320C40 Prozessor · Vektor-Radix FFT
We report a multi parameters cardio-pulmonary (CP) monitoring system with features of low power consumptions (30mA,3.3V), miniaturization (size 25 cm2), and wireless data communications (Frequency 96 MHz) for wearable applications in e-Health. Its target application is forthe evaluation of fitness of CP during exercises. We use aminiature bi-directional hot-wire sensor for respiratory function,an optical sensor for saturated blood oxygen level or plethsymograph, and two surface electrodes for single lead electrocardiograph. The fitness indexes include blood oxygen level, ECG, and respiratory functions, which will be used for the quantitative evaluation of the level of physical activity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
