Appl. No.:

09/855871

Inventors:

Yi Liu - Austin TX
Wei-Lien Hsu - Austin TX
Frank Gorishek - Austin TX

Assignee:

Advanced Micro Devices, Inc. - Austin TX

International Classification:

G06T 920

US Classification:

382266, 382268

Abstract:

The invention, in a first aspect, is a method for mitigating edge effects in a decompressed video image. The method comprises first reads an NÃN group of pixels defining a vertical edge between two blocks in a video frame row by row into N registers, wherein N is a predetermined number defining the length of a filter. The content of the N registers is then transposed and then filtered in the filter. The filtered content of the N registers is then transposed and stored back from where it was read. In other aspects, the invention is a program storage device encoded with instructions that, when executed by a computer, perform such a method; a computer programmed to perform such a method; and a computing system capable of performing such a method.

International Classification:

G06F 1714

US Classification:

708401, 708402

Abstract:

A system and method for carrying out a two-dimensional forward and/or inverse discrete cosine transform is disclosed herein. In one embodiment, the method includes, but is not necessarily limited to: (1) receiving multiple data blocks; (2) grouping together one respective element from each of the multiple data blocks to provide full data vectors for single-instruction-multiple-data (SIMD) floating point instructions; and (3) operating on the full data vectors with SIMD instructions to carry out the two dimensional transform on the multiple data blocks. Preferably the two dimensional transform is carried out by performing a linear transform on each row of the grouped elements, and then performing a linear transform on each column of the grouped elements. The method may further include isolating and arranging the two dimensional transform coefficients to form transform coefficient blocks that correspond to the originally received multiple data blocks. The multiple data blocks may consist of exactly two data blocks.

International Classification:

G06F017/14

US Classification:

708402, 708400

Abstract:

A method is disclosed for performing an inverse discrete cosine transform (IDCT) using a microprocessor having an instruction set that includes SIMD floating-point instructions. In one embodiment, the method includes: (1) receiving a block of integer data having C columns and R rows; and (2) for each row, (a) loading the row data into registers; (b) converting the row data into floating-point form so that the registers each hold two floating-point row data values; and (c) using SIMD floating-point instructions to perform weighted-rotation operations on the values in the registers. Suitable SIMD floating-point instructions include the pswap, pfmul, and pfpnacc instructions. For the row-IDCT, the data values are preferably ordered in the registers so as to permit the use of these instructions. For the column-IDCT, two columns are preferably processed concurrently using SIMD instructions to improve computational efficiency. An intermediate buffer may be used to avoid unnecessary conversions between integer and floating-point format.

International Classification:

C25D 9/02

US Classification:

205229, 205317

Abstract:

A method of forming a bioelectronic device including a protein on an electrically conductive substrate, by electrodepositing aminopolysaccharide chitosan on the substrate while applying a cathodic voltage to the substrate, to form an aminopolysaccharide chitosan film thereon, applying an anodic voltage to the substrate in the presence of NaCl to activate the aminopolysaccharide chitosan film so that it is reactive with protein. The method also optionally includes reacting the aminopolysaccharide film, after activation thereof, with the protein, so that the protein assembles on and is coupled to the substrate, thereby forming a bioelectronic device. The protein can include single or multiple protein species, and including biosensing proteins. Additional methods include biosensing of electrochemically active compounds either present in a sample or generated during a biological recognition event and devices useful in such methods. The resulting devices are useful as sensors in hand-held devices, textiles, garments and the like.

Abstract:

Methods for the generation of hydrogels formed by electrodeposition of an electroaddressable polymer are described. The hydrogels may contain one or more cell populations electroaddressed or electroaddressable to a location within the hydrogel and where the cells of the cell populations are entrapped by the hydrogel and are capable of expansion within the hydrogel and may be releasable from the hydrogel. Further provided are electroaddressable polysaccharide blends for the in-film expansion of a cell population, allowing probing of the cells and formation of immunocomplexes. Further provided are methods of using hydrogels containing electroaddressed or electroaddressable cell populations in in-film bioprocessing methods such as cell-based biosensing, protein-based biosensing, and in studies of cell signaling.
