Fairchild TMC2302A Data Handbook
Summary
The TMC2302A is a high-performance address generator designed for advanced digital image manipulation, supporting complex tasks like rotation, warping, filtering, and rescaling in both 2D and 3D video applications. This component utilizes polynomial generation to precisely remap pixel locations between target and source spaces. The accompanying manual provides comprehensive technical specifications, detailed block diagrams, and functional instructions necessary for system designers building specialized imaging systems, virtual effects generators, or robotics platforms requiring high-precision image transformation capabilities.

Description
supported
Flexible, user-configurable pixel datapath timing structure The TMC2302A, a pin-compatible replacement for the Static convolutional filtering of up to 16 x 16 Pixel (one- TMC2302, is a high-speed self-sequencing address genera- pass), 256 x 256 pixel (two-pass) or 256 x 256 x 256 pixel tor which supports image manipulations such as rotation, (three-pass) windows rescaling, warping, filtering, and resampling. It remaps the User-selectable source image subpixel resolution of pixel locations of a target (display) space back into those of a
-8 -16 source image space. The degree and type of image manipula- to 2
Pin-compatible upgrade to TMC2302 tion is determined by the remapping selected.
24-bit (optional 36-bit) positioning precision within the
source image space, 48-bit internal precision To remap from the target to the source space, this integrated Low power CMOS process circuit computes a series of polynomials of the target space Available in a 120-pin Plastic Pin Grid Array and 120-lead coordinates, based on user-assigned coefficients. Two Metric Quad Flat Pack TMC2302A chips can generate third-order warps of a two- dimensional image, whereas three can second-order warp a three-dimensional image.

Frequently Asked Questions
What types of image transformations can the TMC2302A perform?
It supports complex manipulations including rotation, warping, resampling, and filtering for both two-dimensional and three-dimensional images.
Is this chip compatible with older models?
Yes, it is a pin-compatible upgrade designed to replace the original TMC2302 while improving environmental specifications.
What is the estimated speed for large 3D image resampling?
Nearest-neighbor resampling of a 3D image (128 pixels on a side) takes approximately 53 milliseconds using three functional devices.
Can this component be used as a critical part in life support systems?
No; the product is not authorized for use as a critical component in life support devices or systems without express written approval from Fairchild Semiconductor Corporation.
