TMC2302A

The TMC2302A, a pin-compatible replacement for the TMC2302, is a high-speed self-sequencing address genera-tor which supports image manipulations uch as rotation, rescaling, warping, filtering, and resampling. It remaps the pixel locations of a target (display) space back into those of a source image space. The degree and type of image manipula-tion is determined by the remapping selected.

To remap from the target to the source space, this integrated circuit computes a series of polynomials of the target space coordinates, based on user-assigned coefficients. Two TMC2302A chips can generate third-order warps of a two-dimensional image, whereas three can second-order warp a three-dimensional image.
