[M4IF Technotes] Nancy video codec

[Biswajit Biswas]

Hi All,
Nancy codec is based on a proprietary algorithm called Structured Meta
Scale Polygon, which divides images into blocks of various shapes and
sizes for compression. The current version uses square blocks ranging
from 1 x 1 to 32 x 32 pixels to divide an image, depending on its
complexity.
Nancy uses only the four fundamental processes of arithmetic (addition,
subtraction, multiplication and division), along with comparison and
bit-shift operation.
QCIF compression/decompression at 30fps consumes around 50 MIPS when
using Nancy codec
