Abstract: A method in a computer system of performing a butterfly stage of a complex fast fourier transform of two input signals. First, a packed multiply add is performed on a first packed complex value generated from a first input signal and a set of trigonometric values to generate a first product. Then, a second product is generated which comprises the first product with a sign inverted. A packed add of the second product and a second complex value generated from a second input signal is performed to generate a first result, and the first product and the second complex value to generate a second result.

Abstract: A tensioning assembly for applying tension to portions of a cap is provided. The tensioning assembly increases the tension applied to cylindrical sections of the cap that are located between the cap visor and the back of the cap. The tensioning assembly includes a tensioning disk that is moveable inwardly and outwardly, as well as being rotatable, when an embroidery pattern is being stitched on the cap. The tensioning assembly is connected to a drive apparatus and its position relative thereto can be adjusted, depending upon the size of the cap. A cable adjustment assembly is also preferably included for maintaining desired tension of a cable that is coupled to a drive beam used in providing linear motion that is translated to rotational movement of the cap being embroidered. A holder assembly is connected to the drive apparatus for maintaining desired positioning of the drive beam particularly when the drive apparatus is detached from the computerized embroidery machine.

Abstract: The present invention is a method and apparatus for translating an input character from a source codeset to a target codeset. Structurally, the present invention includes a list of translation tables each having one or more entries. Each entry in a translation table defines a translation from a character in the source codeset to a character in the target codeset. Each translation table also includes an entry condition function and an input normalization function. To translate an input character in the source codeset to the target codeset, the list of translation tables is traversed until an entry condition is found which returns a boolean value of true when called with the input character is passed as a parameter. Then input character is then passed to the input normalization function which returns the index or position of the translation for the input character in the translation table. The contents of the translation table, at the index, is then returned as the translation of the input character.

Abstract: Sputtering processes are carried out at low pressure, of less than one milli-Torr, particularly in the range of 0.05 to 0.5 mTorr, to reduce scattering of the sputtered particles due to collisions with atoms of the process gas, particularly for coating contacts at the bottoms of sub-micron sized holes of high aspect ratios. The sputtering is made possible by provision for a supplemental RF plasma generating source by which RF energy is reactively coupled into the gas within the chamber in close proximity to the surface of a sputtering target, preferably adjacent the periphery thereof. The pressure in the chamber as well as the power to an RF electrode by which the supplemental plasma is energized and the DC power by which the main target is energized are dynamically controlled so that the plasma is sustained at low pressure.

Then, data elements from the first result are interleaved with data elements from the second result to generate a third result.

Abstract: An ionized physical vapor deposition apparatus is provided with a helical RF coil that surrounds the chamber wall opposite a space between a target and a substrate holder. The coil is behind a quartz window in the wall of the chamber, which protects the coil from adverse interaction with plasma. The coil is energized with RF energy, preferably in the 0.1 to 60 MHz range, to form a secondary plasma in a volume of the space between the substrate holder and the main plasma that is adjacent the target. A shield between the space and the dielectric material prevents coating from forming on the window. The shield is formed of a plurality of angled sections that are spaced to facilitate communication of a secondary RF plasma from adjacent the window to the volume of the chamber where the sputtered material is ionized, with the sections angled and spaced to shadow at least most of the target from the window.

Abstract: A method of multiplying and accumulating two sets of values in a computer system. A packed multiply add is performed on a first portion of a first set of values packed into a first source and a first portion of a second set of values packed into a second source to generate a first result. The first result is unpacked into a plurality of values (e.g. two). The plurality of values is then added together to form a resulting accumulation value.

Abstract: A fault isolation system for use in an integrated circuit. The fault isolation system includes multiple input shift registers which are connected end-to-end, serial output to serial input, for convenient interface with a test data input and test data output that are controlled by the test access port controller (tap controller) of conventional JTAG circuitry that is frequently provided in such integrated circuits. The multiple input shift registers include parallel inputs which receive test data from test nodes within functional blocks such as general circuit blocks and linear bus alleys. The multiple input shift registers are efficiently controlled by a global controller which talks to many local controllers. The global controller distributes control signals that are received by the local controllers.

Abstract: A method for executing different sets of instructions that cause a processor to perform different data type operations in a manner that is invisible to various operating system techniques, that promotes good programming practices, and that is invisible to existing software conventions. According to one aspect of the invention, a data processing apparatus executes a first set of instructions of a first instruction type on what at least logically appears to software as a single logical register file. While the data processing apparatus is executing the first set of instructions, the single logical register file appears to be operated as a flat register file. In addition, the data processing apparatus executes a first instruction of a second instruction type using the logical register file. However, while the data processing apparatus is executing the first instruction, the logical register file appears to be operated as a stack referenced register file.

Abstract: Improved solvent systems for the formulation of N-alkyl thiophosphoric triamide urease inhibitors. These formulations enable the preparation of stable concentrated solutions of N-alkyl thiophosphoric triamides for storage, transportation, and eventual impregnation onto solid urea containing fertilizers and incorporation into liquid urea containing fertilizer compositions. These formulations are comprised primarily of a solvent selected from the group consisting of glycols and glycol derivatives. Optionally, in addition to the glycol base solvent, the formulations can contain a co-solvent selected from the group consisting of liquid amides, 2-pyrrolidone and N-alkyl 2-pyrrolidones, and/or a nonionic surfactant selected from the group consisting of alkylaryl polyether alcohols. The presence of the co-solvent and/or surfactant has been found to impart desirable properties to the formulations under certain conditions.
