Low Complexity Pipelined Architecture for Real-Time Generic Video Scaling
A five stage pipelined architecture is proposed to target real-time video resolution conversion in spatial domain. This low complexity design is based on pre-computed memory mapping which computes the geometric position of interpolated pixels and their gray level values based on the scaling factor. The memory map has been conceived using nearest neighbor interpolation technique which simplifies the implementation. The scaling ratio is provided as an input to the hardware architecture before conversion. The design is capable of converting any video frame size in real-time.
