Abstract

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