Fungsi korelasi–rentas kebiasaannya memerlukan masa pengiraan berkomputer yg panjang, maka ia agak sukar untuk menghasil profil halaju dalam masa yang singkat terutama sekali dalam mod masa-nyata. Oleh itu, system pengagihan data dibangunkan dengan menggunakan unit pemprosesan data berganda dan konsep unit pemprosesan data selari untuk mempercepatkan proses penghasilan profil halaju. Penulisan ini juga membentangkan konfigurasi system pemprosesan data yang baru dan bagaimana ia beleh menggantikan unit pemprosesan tunggal untuk mengira profil halaju dengan lebih pantas. Kata kunci: Profil halaju; fungsi korelasi–rentas; sistem pengagihan data The cross–correlation function usually takes a long computation time, so it is quite hard to produce a velocity profile in a short time especially in online mode. Thus, data distribution system is developed by using multiple data processing units and concept of parallel data processing to speed up the process of producing velocity profile. This paper also presents the configuration of new data processing system and how it can replace single processing unit to compute velocity profile faster. Key words: Velocity profile; cross–correlation function; data distribution systemDownloads
