International Classification:

G06F017/50

US Classification:

716 1, 716 12

Abstract:

A 7-track standard cell library having a layout architecture that is designed for fabrication technologies having design rules of 0. 12 microns or smaller. The cells are laid out using a routing grid having horizontal and vertical grid spacings of 0. 4 microns, such that the height of each 7-track standard cell is 2. 8 microns (i. e. , seven track spacings based on a horizontal grid spacing of 0. 4 microns). Power rails are implemented using M1 structures. The seven-track cell height is divided into four tracks on the P-side and three tracks on the N-side. Complex cells include one internal connection line (structure) formed using the third metal layer (M3) that is introduced in a predetermined track (e. g. , the second track from the top of the cell) to facilitate the seven-track layout.

326/040000

Abstract:

Scan chain routing efficiency is improved in an integrated circuit (IC) such as an application specific integrated circuit (ASIC) by defining flip flop groupings prior to place and route. A flip flop grouping specifies the arrangement of multiple flip flops and the scan chain routing through those flip flops. The predetermined flip flop arrangement of the flip flop grouping then prevents undesirable flip flop placements during place and route. The flip flop grouping therefore minimizes the layout impacts of scan insertion while simplifying the place and route process. Different flip flop groupings can be used in a single IC design, and flip flop groupings can be combined with individual flip flops in the IC layout. A flip flop grouping can include control logic for the flip flops. Clock gating logic can be offloaded from the flip flops into the control logic to further improve layout efficiency.

International Classification:

H04N 1/40

US Classification:

358462

Abstract:

A process and system to transform a digital photograph of a text document into a scan-quality image is disclosed. By extracting the document text from the image, and analyzing visual clues from the text, a grid is constructed over the image representing the distortions in the image. Transforming the image to straighten this grid removes distortions introduced by the camera image-capture process. Variations in lighting, the extraction of text line information, and the modeling of curved lines in the image may be corrected.
