Abstract

The software defined receivers are used for deriving of audio signals from radio broadcasting. Audio signals that are acquired from receiver are also obtained as offline from recorded raw data. Therefore, the demodulation algorithm processes can be made offline in JAVA based User Interface(UI). For real time audio processing, it is necessary that demodulation process rate is higher than audio playback rate. In this study, the Intel processor architecture based optimizations are mentioned for real time audio processing. It is observed ten times speed up due to optimizations using JNI method at JAVA based software for demodulation algorithms. The demodulation processes can be made real time due to optimizations for high bandwidth signals, in User Interface

Özet

Telsiz yayınlarından seslerin elde edilmesi için yazılım tabanlı almaçlar kullanılmaktadır. Almaçtan elde edilen sesler aynı zamanda kaydedilmiş ham verilerden çevrimdışı olarak elde edilebilmektedir. Dolayısıyla veri kayıtları üzerinde JAVA tabanlı Kullanıcı Arayüzü’nde çevrimdışı olarak demodülasyon işlemleri yapılabilmektedir. Gerçek zamanlı ses işleme için demodülasyon algoritma işlem hızının ses çaldırma hızından yüksek olması gerekir. Bu çalışmada, gerçek zamanlı ses işleme için Intel işlemci mimarisi tabanlı optimizasyonlardan bahsedilmektedir. JNI yöntemi kullanılarak yapılan optimizasyonlar sayesinde JAVA tabanlı yazılımda demodülasyon işlemleri için 10 kat hızlanma gözlemlenmiştir. Arayüzü’nde demodülasyon işlemleri yüksek bant genişliğine sahip sinyaller için gerçek zamanlı olarak yapılabilmektedir
