Filed:

Aug 1, 2011

Appl. No.:

13/195685

Inventors:

David Alan Brown - Carp, CA
Dzung Tran - San Jose CA, US

Assignee:

PMC-Sierra US, Inc. - Sunnyvale CA

International Classification:

H03H 7/30
H03H 7/40
H03K 5/159

US Classification:

375232, 708323

Abstract:

A data regeneration device regenerates a digital signal in a low-speed pass-through mode of operation, performs an upstream link equalization procedure on an upstream data link in an equalization mode of operation, performs a downstream link equalization procedure on a downstream data link in the equalization mode of operation, and regenerates the digital signal in a high-speed pass-through mode of operation. The data regeneration device transitions seamlessly from the low-speed pass-through mode of operation to the equalization mode of operation in compliance with a communication protocol. Moreover, the data regeneration device synchronizes completion of the upstream link equalization procedure with completion of the downstream link equalization procedure so that the data regeneration device transitions seamlessly from the equalization mode of operation to the high-speed pass-through mode of operation in compliance with the communication protocol.

Filed:

Aug 3, 1998

Appl. No.:

9/128164

Inventors:

Dzung X. Tran - San Jose CA
Kenneth K. Munson - Saratoga CA

Assignee:

Rise Technology Company - Santa Clara CA

International Classification:

G06F 9302

US Classification:

712221

Abstract:

A single chip microprocessor has at least two parallel pipelines that each have multiple processing stages, one of which is an instruction execution stage with a full functioned arithmetic logic unit (ALU). The ALU of one pipeline includes an adder that has the usual two input ports while the adder of the ALU of the other pipeline has at least one extra input port. Two successive arithmetically data dependent instructions are executed by the larger adder alone, while the smaller adder is used as part of a logic circuit that determines the carry bit for the instruction execution result obtained from the larger adder. The smaller adder is thus efficiently used, in an operation where it would otherwise be idle. The additional logic circuitry necessary to determine the carry bit is thus minimized. This additional logic circuitry uses carry bit outputs of both adders, plus the number of adder inputs where the data is inverted in order to execute the instructions, to determine the ultimate carry bit of the instruction execution data.

Appl. No.:

9/274275

Inventors:

Christopher I. Norrie - San Jose CA
Dzung X. Tran - San Jose CA

Assignee:

Rise Technology Company - Santa Clara CA

International Classification:

H03M 700

US Classification:

341 59

Abstract:

A novel method and apparatus is disclosed for locating the first most, or least, significant set bit in a bit-string. The present invention breaks down the bit-string into a plurality of shorter sub-strings so that boolean operations can be performed directly to the shorter sub-strings for determining the location of the most/least significant set bit. Furthermore, this method can be repeatedly used to reduce the length of the shorter sub-string after the most/least significant sub-string is located. Particularly, this method of repeatedly dividing the bit-string greatly increases the speed of locating the set bit.

Inventors:

Dzung X. Tran - San Jose CA

Assignee:

Rise Technology Company - Santa Clara CA

International Classification:

G06F 700

US Classification:

712221

Abstract:

A novel method and apparatus of performing data bit moving functions on a data word using two barrel shifters: a left shifter and a right shifter. The present invention is able to handle both shift and rotate functions using one shifter unit. Specifically, for shift functions, only one of the two shifters is used to perform the shifting function. On the other hand, for rotate functions, both shifters are needed for shifting the data word. The amounts of the right shift and left shift depend on the number defined by the count operand and the specific shift/rotate instruction requested.

International Classification:

G06F 3/01

Abstract:

Particular embodiments described herein provide for an electronic device that can be configured to determine that an unobtrusive gesture has been received on a first electronic device and send a signal to a second electronic device in response to the unobtrusive gesture. The first electronic device can also be configured to receive a signal from the second electronic device, determine an unobtrusive output in response to the signal, and generate an unobtrusive notification in response to the received signal. In an example, the first electronic device is a part of jewelry worn by a user.

International Classification:

G06F 17/30

US Classification:

707769

Abstract:

Methods and systems may provide for obtaining a query image of a scene, wherein the query image includes embedded information and represents the scene at a time of capture. The embedded information may include location data and perspective data. Additionally, user input may be received, wherein the user input identifies a different time than the time of capture. A time-shifted image of the scene may be obtained based on the user input and the embedded information in the query image. Crowd sources and/or other public information sources may also be used to obtain the time-shifted image. In one example, the time-shifted image represents the scene at the different time.
