This paper deals with the design & implementation of a Digital Modulator based on the FPGA. The design is implemented using the Enhanced Direct Digital Synthesis (DDS) Technology. The basic DDS architecture is enhanced with the minimum hardware to facilitate the complete system level support for different kinds of Modulations with minimal FPGA resources. The size of the ROM look up is reduced by using the mapping logic. The Design meets the present Software Define Radio (SDR) requirements and provides the user selection for desired modulation technique to be used. The VHDL programming language is used for modeling the hardware blocks for powerful and flexible programming and to avoid VHDL code generation tools. The design is simulated in the Model Sim Simulation Tool and Synthesized using the Xilinx ISE Synthesis Tool. The architecture is implemented on the SPARTAN-3A FPGA from Xilinx Family in the SPARTAN-3A evaluation board. The experimental results obtained demonstrate the usefulness of the proposed system in terms of the system resources, its capabilities for design, validation and practical implementation purposes.

On the basis of theory analysis, deep research was made about the implementation of force decoupling control of hydraulic shaking table. Because tested specimen has eccentric and height, which produce flywheel moment and overturning moment, and causes the non-synchronization of every exciter, so transient force decouple control (TFDC) strategy is introduced in order to remove this effect. Then, the control strategy was realized based on DSP rapid prototyping. TMS320C2812 DSP was applied to acquire the analogue and digital; TMS320C6713 DSP was used to operate and communicate with embedded processor S3C2410 by dual-RAM in order to improve real-time and rapidity. In the end, this paper presents the implementation of a rapid prototyping control system, which involves the design of DSP algorithms using MATLAB Simulink blocksets, automated code generation in the CCS integrated development environment, and downloading the executable code to the Texas Instruments TMS320C2812 and TMS320C6713.
