A new method for fast transformation is described in this paper. The purpose is real-time transformation at low cost, low power and with small size hardware. Real-time processing is impossible without special hardware. A simple DDA can be easily generalized to an implicit function DDA. The DDA plays a very important role in carrying out fast three-dimensional rotations and projections. Address control memory and brightness control memory, which belong to a lineage of Logic-in-Memory, also do speedy, not only linear transformations, such as affine ones, but nonlinear ones such as mappings. A complex method combining the advantages of both DDA and control memory is proposed. Through concrete examples using digital pictures from a VTR, the effectiveness is confirmed.
