Appl. No.:

10/041932

Inventors:

Jin Chin Wang - Union City CA
Maciek P. Kozyrczak - Bellevue WA

Assignee:

NEC Electronics, Inc. - Santa Clara CA

International Classification:

G06F 1200

US Classification:

711133, 711141, 711159

Abstract:

Described is a data processing system including a processor, a plurality of caches, and main memory, the secondary caches being implemented as being non-inclusive, i. e. , the lower order caches not storing a superset of the data stored in the next higher order cache. The non-inclusive cache structure provides increased flexibility in the storage of data. The operation of a write request operation when the target data line is not found in the primary cache. By using the dirty bit associated with each data line, the interaction between the processor and the primary cache can be reduced. By using the invalidity bit associated with each data line, the interaction between the processor and the primary cache can be reduced.

379 2701, 379 104, 379 24, 37939901

Abstract:

A method for qualifying a telephone line for very-high-bit-rate digital subscriber line (“VDSL”) service is disclosed. Generally, a telephone line for VDSL service is prequalified based on a length of the telephone line. A VDSL rate of the telephone line is measured and it is determined whether to qualify as VDSL data qualified based on the measured VDSL rate and a VDSL rate threshold. A VDSL video quality of the telephone line is measured and it is determined whether to qualify the telephone line as VDSL video qualified based on the measured VDSL video quality. Finally, a network database is updated with the determined VDSL data and video qualifications of the telephone line.

Abstract:

A shape-molding structure of a memory card comprises a circuit substrate, at least one chip, and an encapsulant covering. The upper and lower surfaces of the circuit substrate have a circuit layer and a plurality of electric contacts, respectively. The chip is located on the upper surface of the circuit substrate and electrically connected with the circuit layer. The encapsulant covering is formed by using a mold to press encapsulant entering at least one encapsulant inlet provided on at least one side surface of the circuit substrate. The encapsulant covering encapsulates all the above components with only the electric contacts exposed. A trace mark of the encapsulant inlet remaining on the encapsulant covering is then cut to obtain a shape-molding structure of memory card with an smooth and intact outer appearance.

US Classification:

370228, 34082501

Abstract:

A dual-mode broadband modem operative to operate in a service mode and a surveillance mode is disclosed. Generally, the dual-mode broadband modem comprises a primary communication device; a secondary communication device; a central processing unit in communication with the primary and secondary communication devices; and a memory unit in communication with the central processing unit. In the service mode, the primary communication device communicates with a broadband service provider and the central processing unit stores historical information regarding performance of the primary communication device in the memory unit. If an interruption in broadband service is detected, or the performance of the primary communication device falls below a predetermined threshold, the dual-mode broadband modem switches to surveillance mode and the secondary communication device is activated. The secondary communication device communicates with the broadband service provider to send at least a portion of the historical information regarding performance of the primary communication device to the broadband service provider for processing to determine a source of the interruption in broadband service or a source of the decreased performance of the primary communication device.
