US Classification:

709218, 709203, 709201, 370235

Abstract:

An architecture for controlling a multiprocessing system to provide at least one network service to subscriber data packets transmitted in the system using a plurality of compute elements, comprising a management compute element including service set-up information for at least one service and at least one processing compute element applying said at least one network service to said data packets and communicating service set-up information with the management compute element in order to perform service specific operations on data packets. In a further embodiment, a method of controlling a processing system including a plurality of processors is disclosed. The method comprises the steps of operating at least one of said processors as a control authority providing service provisioning information for a subscriber; and operating a set of processors as a service specific compute element responsive to the control authority, receiving provisioning information from the subscriber and performing service specific instructions on data packets to provide IP content services.

US Classification:

257295, 438 3, 257532, 257E21008, 257E29342, 257E27016

Abstract:

An ammonia-free method of depositing silicon nitride by way of plasma-enhanced chemical vapor deposition (PECVD). Source gases of silane (SiH) and nitrogen (N) are provided to a parallel-plate plasma reactor, in which energy is capacitively coupled to the plasma, and in which the wafer being processed has been placed at a support electrode. Low-frequency RF energy (e.g., 360 kHz) is applied to the support electrode; high-frequency RF energy (e.g., 13.56 MHz) is optionally provided to the parallel electrode. Process temperature is above 350 C., at a pressure of about 2.5 torr. Any hydrogen present in the resulting silicon nitride film is bound by N—H bonds rather than Si—H bonds, and is thus more strongly bound to the film. The silicon nitride can serve as passivation for ferroelectric material that may degrade electrically if contaminated by hydrogen.

US Classification:

39575002

Abstract:

A power management system for a personal computer comprises a power management processor, a switchable power supply and a keep alive power supply. The processor is powered by the keep alive power supply that continuously provides power. The computer is powered by a power supply that is switchable in response to a control signal. The processor preferably controls the switchable power supply. The processor is coupled to receive external device interrupts from a plurality of external devices that instruct the processor when to turn the switchable power supply on and off. The processor is also coupled to the computer through an interface. The power management system also includes a method for turning the computer on and off. A preferred method uses the processor to control the power provided to the computer. The preferred method also uses the processor to dictate whether the computer will to perform a long boot that brings the computer to an operational state, identifies the computer's configuration, and tests memory, or a short boot that brings the computer to an operational state in a much shorter time.

International Classification:

G06F 700

US Classification:

39580024

Abstract:

Software creates a compressed instruction format for a VLIW processor which allows greater efficiency in use of cache and memory. Instructions are byte aligned and variable length. Branch targets are uncompressed. Format bits specify how many issue slots are used in a following instruction. NOPS are not stored in memory. Individual operations are compressed according to features such as whether they are resultless, guarded, short, zeroary, unary, or binary. Instructions are stored in compressed form in memory and in cache. Instructions are decompressed on the fly after being read out from cache.
