Abstract :
This paper presents a circuit dedicated to real time geometrical transforms of pictures. The supported transforms are third degree polynomials of two variables. The post-processing is performed by a bilinear filter. An embedded DSP core is in charge of high level, low rate, control tasks while a set of hard wired units is in charge of computing intensive low level tasks
