Abstract: A display processor integrated circuit (for example, for a television or for a digital camera) includes a display processor portion and an on-chip programmable logic portion. The on-chip programmable logic portion can be configured or programmed to implement custom video and/or image enhancement functions. Accordingly, an individual television or camera manufacturer can have his/her own custom enhancement function incorporated into the display processor integrated circuit by having the programmable logic portion configured or programmed appropriately. In one embodiment, the programming of the programmable logic portion involves changing just one mask, thereby reducing the cost, complexity and time associated with implementing the custom video/image enhancement function.

Abstract: A method is disclosed whereby an inexpensive integrated circuit is provided for use in high volume electronic consumer devices of different makes, wherein each different make must perform a different special function. A common function required in all the different makes is realized in a substantially non-customizable portion. A dense mask-programmable portion is provided for realizing a special function. Interface circuitry is provided that enables an external FPGA to perform the special function at system operating speeds during system development. After system development, the circuitry implemented in the external FPGA is technology-mapped to the mask-programmable portion. A single mask is fashioned such that versions of the integrated circuit are produced with their mask-programmable portions customized to perform the special function. I/O terminals that were used to couple to the external FPGA during system development are usable during normal operation to provide system board access to circuitry within the mask-programmable portion.

Abstract: A display processor integrated circuit includes a display processor portion and an on-chip programmable logic portion. The programmable logic portion can be configured to implement custom video and/or image enhancement functions. The display processor portion performs block-based motion detection. If no motion is detected for a given block of pixels, then interline gaps in the block are filled using temporal interpolation. If motion is detected, then interline gaps are filled using spatial interpolation. To maintain accuracy without unduly increasing computational complexity, a less complex high angle spatial interpolation method is employed where a low angle tilt condition is not detected. A more computationally intensive low angle spatial interpolation method can therefore be employed in low angle tilt conditions. Integrated circuit cost is reduced by employing pipelining to write parts of segment buffers at the same time that other parts are being read to perform the interpolation process.
