Filed:

Oct 30, 2009

Appl. No.:

12/610208

Inventors:

David A. Warren - El Dorado Hills CA, US

International Classification:

G06F 15/76
G06F 9/02
G06F 9/30

US Classification:

712 28, 712220, 712E09002, 712E09016

Abstract:

A hardware pipeline has a number of rows including a first row, a last row, and an intermediate row between the first row and the last row. Each row stores a number of bytes of data as the data moves through the pipeline on a row-by-row basis from the first row towards the last row. A mechanism performs a first macro on the data beginning at the first row. The mechanism performs a second macro different than the first macro on the data beginning at the intermediate row where the first macro has been completely performed when the data has reached the intermediate row. The first and second macros each include a number of modifications of the data as the data moves through the pipeline to effect a complete transformation of the data. The complete transformation of the first macro is different than the complete transformation of the second data.

Appl. No.:

13/259307

Inventors:

David A. Warren - El Dorado Hills CA, US

International Classification:

G06F 21/00

US Classification:

726 22

Abstract:

A device includes a pipeline and a detector that are both implemented at least in hardware. Data is moved through the pipeline to perform processing of the data unrelated to detection of malicious code. The detector detects the malicious code within the data as the data is moved through the pipeline, in parallel with the processing of the data as the data is moved through the pipeline. The detector detects the malicious code within the data as the data is moved through the pipeline without delaying movement of the data into, through, and out of the pipeline.

David A. Warren - El Dorado Hills CA, US
Bruce E. LaVigne - Roseville CA, US

International Classification:

G06F 21/64

US Classification:

726 23

Abstract:

Data is moved through a pipeline as processing of the data unrelated to detection of pattern is performed. The detector detects the pattern within the data at a predetermined location or based on a predetermined reference as the data is moved through the pipeline, in parallel with the processing of the data as the data is moved through the pipeline. The detector detects the pattern within the data as the data is moved through the pipeline without delaying movement of the data into, through, and out of the pipeline.

David Warren - El Dorado Hills CA, US
Bruce E. LaVigne - Roseville CA, US
Jonathan E. Greenlaw - Roseville CA, US

International Classification:

H04L 29/06

US Classification:

370392

Abstract:

A method for mitigating detected patterns in a network device is described herein. A packet is moved through a first pipeline of the network device, to perform processing of the packet. A pattern is detected within the packet. In response to detecting the pattern, a hardware component of the network device generates a flag as the packet is moving through the first pipeline, in parallel with the processing of the packet. One or more forwarding policies associated with the packet are determined using the flag.

Thomas A. Keaveny - Auburn CA, US

International Classification:

G06F 9/30

US Classification:

712205, 712214

Abstract:

Embodiments herein relate to forwarding an instruction based on predication criteria. A predicate state associated with a packet of data is to be compared to an instruction associated with the predication criteria. The instruction is to be forwarded to an execution unit if the predication criteria includes or matches the predicate state of the packet.

International Classification:

H03B 508
H03B 518

US Classification:

331 66

Abstract:

An optical injection locking oscillator is comtemplated having a tuning device. The tuning device generates a DC voltage proportional to the resonant frequency of a modulated light used to injection lock the free running oscillator. The DC voltage is applied to a varactor capacitor within the oscillator to bring the frequency of oscillation within a close proximity to the modulating frequency of the light. This facilitates injection locking, whereas frequencies of oscillation outside a certain locking range will not facilitate injection locking. The modulated light then locks the oscillator into a desired resonant frequency. A second embodiment contemplates using a YIG oscillator regulated by a DC current generated within the tuning device.
