Abstract: The backbones of the multimedia applications are the Digital Signal Processing (DSP) blocks. And among the multimedia, videos and images most of them are occupied with the using of these DSP blocks. The version and auditory sense of human beings are not as sensitive as machines, and this limitation allows these algorithms ' outputs to be numerically approximate rather than accurate. This leads to a new branch-imprecise computation, which can tolerate some errors and at the same time do not have significant impacts on the dissemination of information. Imprecise computation can be achieved at different levels such as logic, architecture and algorithm. However, less published papers are focus on the logic reducing. The target of the dissertation is to reduce the complexity of the logic. The propagation delay, power consumption and power-delay product are three important parameters which are used to compare the simulation results six different 4-bit IFA designs at different supply voltage and test the performance of the designs at higher frequencies.
