Fault-tolerant display image-data-manipulation unit for system-on-panel

Abstract

Bit-partitioned and conventional shifts, as well as type transformations of multimedia data, are frequently used for display image-processing systems. A data manipulation unit with fault-recovery capability based on redundancies is proposed for system-on-panel with low processing technology yield. Utilizing data manipulations that are similar to normal shift operation, a proposed data-manipulation unit is designed with a few additional paths added to the existing barrel shifter. The design methodologies are verified with FPGA and the performance is evaluated in terms of the advantages.
