To meet increasing users' demand in portable system display panel such as less weight, power, size as well as more features, a fault tolerant image processing coprocessor integration on display panel with poly Si is proposed. Due to low yield of poly Si, the coprocessor integration needs high degree of fault tolerance for commercial use. This paper presents not only how to detect but also how to recover the faults in the coprocessor using a novel fault detection routine based on simultaneous main and the coprocessor execution and an efficient redundancy scheme. The proposed fault tolerance methodologies can play an important role in system on panel implementation to be realized in the near future
