Reconfigurable implementation of recursive DCT kernels for reduced quantization noise

By Andrew G. Dempster, Robert Beck, Suleyman S. Demirsoy and Izzet Kale


Time multiplexed implementations of the recursive DCT\ud processors are widely used in many multimedia and compression applications. Recently proposed three Goertzel kernels offer significant improvement (up to 90 %) in the noise performance of the time-multiplexed architecture to allow word-length specifications get reduced. In this paper, a highly optimized reconfigurable DCT architecture is proposed that can perform the function of three different kemels (Type A, B and C) on Virtex FPGA\u
