Kombinerad DSP- och FPGA-lösning för en bildbehandlingsapplikation
This Master's Thesis describes the design of a new system where a digital signal processor has been added to an existing imaging system consisting of field programmable gate arrays. The new system will offer a higher degree of flexibility by considerably shortening the design time and make it possible to implement more complex algorithms than the existing ones. The choice of system architecture and a test implementation are discussed. The test implementation consists of a program for the digital signal processor and VHDL code for one of the field programmable gate arrays. The code for the digital signal processor was designed for testing on an evaluation board from Texas Instruments. The evaluation board is connected to a computer, which runs a Windows program to visualize the result. The choice of algorithm has not been made yet. In the test implementation a skewing algorithm is used as an example. Two implementations of the skewing algorithm has been optimized, one fix point version and one floating point version.
