Abilitiy tính của Texas Instrument TMS320VC5510 DSK với các ngôn ngữ chương trình khác nhau là điều tra về đo lường thời gian tối thiểu của DSP. Các bước của mô phỏng Monte Carlo nhúng vào flash của DSK thông qua giao diện JTAG của DSK. | VNU Journal of Science Mathematics - Physics 26 2010 61-70 Monte Carlo simulations and DSP application for optical parameter measurement Nguyen Tuan Anil1 . Bach Gia Duong2 Nguyen Xuan Thai1 National Centre for Technological Progress 2College of Technology Vietnam National University Hanoi Received 9 February 2010 Abstract. The Texas Instrument TMS320VC5510 DSK s calculation abilitiy with different program languages is investigated for minimum the DSP s measurement time. The steps of Monte Carlo simulations embedded into the DSK s flash through the DSK s JTAG interface for optical parameters measurement including absorption coefficient ma scattering coefficient ms and anisotropy g are presented. The obtained results for diluted milk standard samples are also reported. 1. Introduction Light propagation in turbid media can be described by the Radiance Transport Equation with three optical specified parameters absorption coefficient Ra scattering coefficient ms and anisotropy g 1 . The determination of these parameters can be taken by different methods the approximate models such as Kubelka-Munk 2 or Monte Carlo simulations. The Kubelka-Munk model gives quick result as it bases on direct calculation of the backward scattering R d forward scattering Td and the collimated light Tc 3 . However it is not as exact as the result given by Monte Carlo simulations. Monte Carlo simulations has developed since 1940s even though nowadays its application has been found in many fields due to it is a mathematic method that give exact results 4 5 . Nevertheless Monte Carlo simulations require a great volume of calculation. In other words it takes much time for calculation thus not suitable with on-line monitoring system. To cope with this Monte Carlo simulations has been embedded into DSP environment - the Texas Instrument TMS320VC5510 DSK kit 6 . With a DSP s special structure such as parallel and pipe-line techniques this method allows reducing the calculation time. 2. Theory Monte
