... TTL compatible and (except for the three-state output enable) are registered on the rising edge of CLK. The TMC2246A is uniquely suited to performing pixel inter- polation in image manipulation and filtering applications companion to the Fairchild Semiconductor TMC2301 and TMC2302 Image Manipulation Sequencers, the TMC2246A can execute a bilinear interpolation of an image (4-pixel ker- nels) at real-time video rates ...

... OCEN CLK OEN Functional Description The TMC2246A Image Filter is a flexible multiplier-summer array which computes the accumulated sum of four 11x10 bit products, allowing word growth bits. The inputs are user-configurable, allowing latching of either the 10- or 11-bit input data. The data format is user-selectable between integer or fractional two’ ...
