Sequence alignment and sequence database similarity searching are among the most important and challenging task in bio informatics, and are used for several purposes, including protein function prediction. An efficient parallelisation of the Smith-Waterman sequence alignment algorithm using parallel processing in the form of SIMD (Single-Instruction, Multiple-Data) technology is presented. The method has been implementation using the MMX (MultiMedia eXtensions) and SSE (Streaming SIMD Extensions) technology that is embedded in Intel's latest microprocessors, but the method can also be implemented using similar technology existing in other modern microprocessors. Near eight-fold speed-up relative to the fastest previously an optimised eight-way parallel processing approach achieved know non-parallel Smith-Waterman implementation on the same hardware. A speed of about 200 million cell updates per second has been obtained on a single Intel Pentium III 500 MHz microprocessor.

A new method and apparatus for visualization and manipulation of real 3-D objects are disclosed. This new approach utilizes compressed digital video taking advantage of modern video compression technology. The entire system consists of the image acquisition device, the viewing/manipulation program and the 3-D image database. The system first captures images of the object from all possible view angles as a sequence of images (a video). As neighboring images within the sequence will generally be similar, the sequence will be amenable to standard video compression techniques such as MPEG. The acquired video data (rendition of a real 3-D object) is then stored into a database for later access, for instance, over the Internet.

Through specially developed software, the stored data can be manipulated while viewing the object. The user simply inputs—via a mouse, for instance—the view angle and the software automatically displays the appropriate frame within the video (stored data). The software allows various object manipulations such as rotation in arbitrary direction, as well as zoom, pan, etc. A particular implementation of the viewing program using a Pentium III processor, randomly accessing an MPEG sequence, through pre-decoding of certain anchor frames, is able to decode fast enough for users to perform real-time manipulation of the object.

The captured 3-D image data of an object is stored into a centralized (or distributed) database and users may access the data through the assigned URL for the object over the Internet. The data may or may not be password protected. As such, the overall system is an implementation of a one-stop service for individuals wishing to provide 3-D visualization of real 3-D objects over the Internet.

The method of extracting popular songs' key section is used in the music audition and belongs to the field of music signal analysis.

A microprocessor that executes a repeat prefetch instruction (REP PREFETCH). The REP PREFETCH prefetches multiple cache lines, wherein the number of cache lines is specifiable in the instruction. The instruction is specified by the Pentium III PREFETCH opcode preceded by the REP string instruction prefix. The programmer specifies the count of cache lines to be prefetched in the ECX register, similarly to the repeat count of a REP string instruction. The effective address of the first cache line is specified similar to the conventional PREFETCH instruction. The REP PREFETCH instruction stops if the address of the current prefetch cache line misses in the TLB, or if the current processor level changes. Additionally, a line is prefetched only if the number of free response buffers is above a programmable threshold. The prefetches are performed at a lower priority than other activities needing access to the cache or TLB.
