This Paper deals with a design, making a prtotype and test methods of Real-time towed Line Array Sensor Data processing board for fast data communication and long range data transmission with SFM(Serial FPDP Module) through Optic-fiber channel. Towed line array sensors are installed in Frigate and the each LAS A, B, C group data from LAS is packed a previously agreed protocol and transmitted to the signal processing unit. Considering the limited space of VME 6U size, LAS Data processing board is designed with MPC8265 PowerPC Controller of Freescale for main system control and Altera's CycloneIII FPGA for sensor data packing, self-test simulation data generation, S/W FIFO et cetera. LAS Data processing board have VxWorks, the RTOS(Real Time Operating System) that present many device drivers, peripheral control libraries on board for real-time data processing.
