Abstract :
A novel embedded OpenRISC platform was developed with Altera FPGA, its source codes were based on OpenRISC1200 intellectual property (IP) core and uClinux. Five algorithms of video special effects for camera applications were proposed and integrated in the drivers, which included mirror effect, line-scanning effect, diff effect, edge blur effect and noise effect. Moreover, a front-end program interface was provided for calling specific application, which was integrated at the level of drivers rather than application program layer. Emulations and experiments show that it can satisfy application requirements.
