Abstract: A method of coding a quantization matrix (QM) comprising non-uniformly downsampling the QM to generate a plurality of downsampled quantization coefficients. Also, an apparatus used in video encoding comprising a processor configured to non-uniformly downsample a QM to generate a plurality of downsampled quantization coefficients, scan the downsampled quantization coefficients, and encode the downsampled quantization coefficients based on scanning the downsampled quantization coefficients to generate encoded coefficients, and a transmitter coupled to the processor and configured to transmit a bitstream comprising a picture parameter set containing the encoded coefficients.

Abstract: Placement or floorplanning of an integrated circuit is performed by constructing legal layouts at every level of a hierarchy of subsets of modules representing the integrated circuit, by scalably incorporating legalization into each level of the hierarchy, so that satisfiability of constraints is explicitly enforced at every level, in order to eliminate backtracking and post-hoc legalization.

Abstract: The present invention discloses a method, apparatus, and article of manufacture for wire width planning and performance optimization for very large scale integration (VLSI) interconnects. Two simplified wire sizing schemes are described for the VLSI interconnect, namely a single-width sizing (1-WS) or a two-width sizing (2-WS). These simplified wire sizing schemes have near optimal performance as compared to more complex wire sizing schemes with many or even an infinite number of wire widths. A wire width planning method is then described to determine a small set of globally optimal wire widths for the VLSI interconnects in a range of lengths. It is concluded that near optimal interconnect performance can be achieved by using such pre-designed, limited number of wire widths (usually two-width design is adequate). The layout for the VLSI interconnects is then generated and optimized using the limited number of wire widths.
