An Analog Design of 2D DCT Processor

This paper presents the design of a processor for the computation of 8×8 two dimensional Discrete Cosine Transform (2D-DCT) in analog domain. In the implementation, current mode modules are used. Suitable architectures for analog implementation with optimal power and hardware usage have been selected for the implementation of the DCT processor design. A digital design of the DCT processor using components such as flip flops, multiplexers which are inferred from the hardware description in behavioral model is done for performance comparison. The analog design is found to be suitable for power-constrained applications whereas digital design is suitable for accuracy-specific applications.
