Abstract:
PROBLEM TO BE SOLVED: To improve a rake receiver used when spread-spectrum signal is demodulated. SOLUTION: An architecture for a rake receiver of a CDMA demodulator utilizes a common data path for signal processing. This common data bus is shared by all channels (either physical channels or propagation paths within physical channels) to avoid redundant calculations, reduce circuit space, and reduce power consumption. The sharing of the common data path for demodulation is made in a time division manner, with each channel being given sequential access to the data bus to perform all or part of a given function (for example, de-scramble, de-spreading, de-rotating, and de-skewing accumulation).

PROBLEM TO BE SOLVED: To provide an improved image processing system and a method to remove and smooth out irregularities from a 3D image representation from multiple 2D image views. SOLUTION: The image processing system and the method are provided to remove and smooth out irregularities from 3D image information reproduced from one scene, specially, multiple 2D image views from a uniform surface of an object in the scene. In this method, a window that overlaps a plurality of pixels of one of a plurality of 2D image views of a scene is defined. Each pixel is associated with predefined 3D depth information and further associated with a matching curve. A subject pixel is located within the plurality of pixels overlapped by the window. An average 3D depth information associated with the plurality of pixels overlapped by the window is calculated and if the calculated average 3D depth information is within an error region of the matching curve associated with the subject pixel, the calculated average 3D depth information is assigned to the 3D depth information of the subject pixel.

Abstract:
PROBLEM TO BE SOLVED: To provide new fetch branch architecture for reducing branch penalty without branch prediction. SOLUTION: In lieu of the branch prediction, a merged fetch-branch unit operates in parallel with a decode unit in a processor. Upon detection of a branch instruction within a group of one or more fetched instructions, any instructions preceding the branch are marked as regular instructions, the branch instruction is marked as such and any instructions following the branch are marked as sequential instructions. Within two cycles, sequential instructions following the last fetched instruction are retrieved and marked, target instructions beginning at the branch target address are retrieved and marked and the branch is resolved. Either the sequential or target instructions are then dropped depending on the branch resolution, incurring a fixed, 1 cycle branch penalty. COPYRIGHT: (C)2003,JPO
Abstract:
PROBLEM TO BE SOLVED: To provide an improved servo circuit and a method for detecting a servo wedge on the spin-up of a data storage disk. SOLUTION: A servo circuit includes a servo channel and a processor. The servo channel recovers servo data from servo wedges that identify respective data sectors on a data-storage disk. The processor detects one of the servo wedges on spin up of the disk, i.e., while the disk is attaining or after the disk attains an operating speed. By detecting a servo wedge instead of a spin-up wedge to determine an initial head position on disk spin up, such a servo circuit allows one to increase the disk's storage capacity by reducing the number of, or altogether eliminating, spin-up servo wedges from the disk.

Abstract:
PROBLEM TO BE SOLVED: To provide a device and a method capable of detecting temperature precisely. SOLUTION: An illustrative embodiment of this invention has a first oscillator circuit which generates a first signal having a frequency depending on a temperature detected. A differential circuit determines the difference in frequencies between the first signal and a second signal having a frequency which is substantially independent of the temperature, and generates a differential signal having a pulse number based on the difference. A counter circuit, in response to this differential circuit, offsets a predetermined temperature level based on the pulse appeared on the differential signal in order to gain an output signal representing a temperature detected.
