The main purpose of this thesis was to contribute to the development and to the design of anembedded system for multimedia by using the HW/SW methodology (codesign). A library offlexible IP cores (Intellectual Property) for video applications was created. Within thisframework, a hardware platform for video acquisition and video restitution was achieved inorder to evaluate the codesign methodology approach and to study the video processingalgorithm. We have studied and implemented the H.263 video encoder from the UIT-Torganism. The frequency of our platform is about 120 MHz. The whole development wasexecuted under μClinux Operating System and controlled by the NIOS II processor. TheH.263 encoder was developed with different hardware accelerators for the SAD, TCD/TCDIand Q/QI operations and permits finally to code video sequences at QCIF@15Hz.
