- Abstract
- System-on-display panel design methodologies are proposed with the purpose of integrating DCT and IDCT on display panels for image codec and peripheral systems so as to reduce the bus data rate, memory size and power consumption. Unified constant geometry algorithms and architectures including recursive additions are proposed for DCT and IDCT butterfly computation, recursive additions and interconnections between stages. These schemes facilitate VLSI implementation and improve fault tolerance, suitable for low-yield SOP processing technologies through duplicate use of a PE as all the butterfly and recursive addition stages are composed and interconnected in a regular fashion. Efficient redundancy replacement methodologies optimizing the computation speed and the amount of hardware in various application areas are also described with testability and reliability issues. Finally, a performance analysis of speed, hardware and interconnection complexity is described with the proposed work's advantages.
