Abstract:
PROBLEM TO BE SOLVED: To generate a reference clock by using a downstream reception USB signal transmitted by a host computer or a hub. SOLUTION: A USB device having a free-running oscillator generates a local clock signal in response to a signal on a universal serial bus (USB). The oscillator is substantially stable and operates at a frequency known for substantial incorrectness. A single end bit serial signal is extracted from a reception signal transmitted by a USB host computer or a hub, and a timing signal is activated by responding to it. A bit pattern is detected and intervals are measured in the single end bit serial signal, and the timing signal is activated in that period. A period P of the local clock signal is adjusted in response to one of the measured intervals. COPYRIGHT: (C)2004,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide an improved technique for extending or alternating a processor instruction set architecture. SOLUTION: The processor architecture uses a split-instruction transaction so as to supply an extension unit with an operand and an instruction and to retrieve results from the extension unit and supports an electrical interface for coupling a processor core to one or more than one coprocessor extension units executing a computational instruction. The generic instructions for sending an operation and data to the extension unit and/or retrieving data from the extension unit allow a new computational instruction to be introduced without regeneration of the processor architecture. Support for a plurality of extension units and/or a plurality of execution pipes within each extension unit, multi-cycle execution latencies and different execution latencies between or within the extension units, extension instruction predicates, and for handling result save/restore on the processor core install and the interrupt is included.

Abstract:
PROBLEM TO BE SOLVED: To reduce the power consumption of cache access in a processor without substantially degrading performance. SOLUTION: For instruction clusters for which no significant performance penalty such as execution of hardware loops is incurred, a processor automatically and dynamically switches to a pipelined two-cycle access to an associated associative cache rather than a single-cycle access. An access involving more than one cycle uses less power because only the hit way within the cache memory is accessed rather than all ways within the indexed cache line. To maintain performance, the single-cycle cache access is utilized in all remaining instructions. In addition, in the case that instruction clusters within a hardware loop fit entirely within a pre-fetch buffer, the cache sub-system is idled for remaining iterations of the hardware loop to further reduce power consumption.

Abstract:
PROBLEM TO BE SOLVED: To provide a sensor device manufactured using an organic semiconductor material. SOLUTION: Sensor cells are arranged in the form of an array within an organic semiconductor layer. A row and column selection circuit addresses one cell of the array at a time to determine the presence of an object contacting or located in proximity to a detection surface above each cell, e.g., the protruding or recessed part of a fingerprint. A control circuit can be provided inside either a companion silicon chip or a second layer made from an organic semiconductor material in order to communicate with the array and an associated system processor. The array consisting of the sensor cells can be manufactured using a flexible polymer substrate. The substrate is peeled and disposed of after contacts are patterned on the organic semiconductor layer. The organic semiconductor layer is usable together with a reactive interface layer which is made redundant to detect a specific chemical material in a test medium. COPYRIGHT: (C)2004,JPO

Abstract:
PROBLEM TO BE SOLVED: To provide a technique for forming a contact opening which is hardly corroded when an interconnecting layer is formed. SOLUTION: A contact opening is formed penetrating through an insulating layer 34 so that it has a straight sidewall part 42 and a bowl-shaped sidewall part 40. The bowl-shaped sidewall part 40 is located close to the top part of the insulating layer 34 to make the top part of the contact opening wider in diameter than its base. A conductive material 46 is formed inside the contact opening, electrically coming into contact with a lower conductive layer 32. The conductive material 46 forms a plug 47 having an enlarged head 52. The enlarged head 52 protects a barrier layer 45 located inside the contact opening against anisotropic etching which is carried out later. Therefore, when an electric interconnecting layer 48 of aluminum or the like is formed over the contact plug 47, the contact plug serves as an etching stopper to protect the barrier layer inside the contact opening against etching.

Abstract:
PROBLEM TO BE SOLVED: To provide technologies for reducing an error rate of data to be transferred or stored in a communication and a storage system. SOLUTION: A feedback equalizer circuit provides a feedback equalizer signal for canceling undesired distortion in an input signal. A summing circuit is responsive to the input signal and the feedback equalizer signal to provide a corrected sample signal to a symbol detector circuit. A feedback modification circuit is responsive to the corrected sample being within one of a plurality of valid symbol windows to feed back the detected symbol to the feedback equalizer and is responsive to the corrected sample being within one of a plurality of marginal threshold windows to feed back a corresponding intermediate value to the feedback equalizer.
