摘要： Techniques are described for decoupling fetching of an instruction stored in a main program memory from earliest execution of the instruction. An indirect execution method and program instructions to support such execution are addressed. In addition, an improved indirect deferred execution processor (DXP) VLIW architecture is described which supports a scalable array of memory centric processor elements that do not require local load and store units.

摘要： Efficient computation of complex multiplication results and very efficient fast Fourier transforms (FFTs) are provided. A parallel array VLIW digital signal processor is employed along with specialized complex multiplication instructions and communication operations between the processing elements which are overlapped with computation to provide very high performance operation. Successive iterations of a loop of tightly packed VLIWs are used allowing the complex multiplication pipeline hardware to be efficiently used. In addition, efficient techniques for supporting combined multiply accumulate operations are described.

摘要： Video sequence processing is described with various filtering rules applied to extract dominant features for content based video sequence identification. Active regions are determined in video frames of a video sequence. Video frames are selected in response to temporal statistical characteristics of the determined active regions. A two pass analysis is used to detect a set of initial interest points and interest regions in the selected video frames to reduce the effective area of images that are refined by complex filters that provide accurate region characterizations resistant to image distortion for identification of the video frames in the video sequence. Extracted features and descriptors are robust with respect to image scaling, aspect ratio change, rotation, camera viewpoint change, illumination and contrast change, video compression/decompression artifacts and noise. Compact, representative signatures are generated for video sequences to provide effective query video matching and retrieval in a large video database.

摘要： Techniques are described for efficient reordering of data and performing data exchanges within a register file or memory, or in general, any device storing data that is accessible through a set of addressable locations. An address translator is placed in the path of all or a selected set of address busses to a storage device to provide a programmable and selectable means of translating the storage device addresses. An effect of this translation is that the data stored in one pattern may be accessed and stored in another pattern or accessed, processed and stored in another pattern. The address translation operation may be carried out in a single cycle, does not involve the physical movement of data in swap operations, allows data to effectively be ordered more efficiently for algorithmic processing and therefore saves power.

摘要： Techniques are described for improving accuracy and speed of video fingerprinting and identification by using video frame color and intensity information. Multiple approaches for generating a novel signature based on video frame color information are described. One is based on spatial distribution of pixel intensities with reference to derived color groups, while another is based on thresholding a joint histogram of pixel intensity, color, and spatial coordinates. These color based signatures can be deployed either as primary video content signatures, or as hash traversal signatures used to improve speed of an initial stage of video data base search procedures. They can also be used as secondary signatures during a video signature data base search with primary video content signatures, to help disambiguate possible false positive matches, and to improve marginal matches which might not be identified otherwise.

摘要： An architecture for a multimedia search system is described. To perform similarity matching of multimedia query frames against reference content, reference database comprising of a cluster index using cluster keys to perform similarity matching and a multimedia index to perform sequence matching is built. Methods to update and maintain the reference database that enables addition and removal of the multimedia contents, including portions of multimedia content, from the reference database in a running system are described. Hierarchical multi-level partitioning methods to organize the reference database are presented. Smart partitioning of the reference multimedia content according to the nature of the multimedia content, and according to the popularity among the social media, that supports scalable fast multimedia identification is also presented. A caching mechanism for multimedia search queries in a centralized or in a decentralized distributed system and a client based local multimedia search system enabling multimedia tracking are described.

摘要： Methods, apparatus, and computer-readable media are described for generating a credible market value that is utilized to produce a listing price for a property with reduced risk of a substantial reduction in the listing price before selling the property and for assessing risk of incorrectly pricing a property. A subject property, selected comparables, and selected comparables having multiple sales are imported from one or more databases for analysis. Information that is imported may include, for example, property features, original listing prices, record of days on the market, and a final listing price and sales price for each property that was sold. A market analysis process is run to produce relative market assessments and a residential value process is run including appreciation calculations based on the comparable properties having multiple sales to produce the credible market value. Graphs are plotted and other computer outputs are provided to identify the risk of incorrectly pricing a property and to illustrate that risk to a potential seller. Additionally, tools are provided to readily illustrate how changes in underlying assumptions affect the analysis.

摘要： A connector for connecting surface mount devices, such as light emitting diodes (LEDs), to printed circuit boards (PCBs). The connector may be prepackage with an LED assembly or on a PCB to which the LED assembly will be mounted. Connection complexity can be moved from the PCB to the connector, and LED assemblies may be customized differently for different customers. One to many and many to one connections are readily supported with variations on the connector.

摘要： The overall architecture and details of a scalable video fingerprinting and identification system that is robust with respect to many classes of video distortions is described. In this system, a fingerprint for a piece of multimedia content is composed of a number of compact signatures, along with traversal hash signatures and associated metadata. Numerical descriptors are generated for features found in a multimedia clip, signatures are generated from these descriptors, and a reference signature database is constructed from these signatures. Query signatures are also generated for a query multimedia clip. These query signatures are searched against the reference database using a fast similarity search procedure, to produce a candidate list of matching signatures. This candidate list is further analyzed to find the most likely reference matches. Signature correlation is performed between the likely reference matches and the query clip to improve detection accuracy.
