By forming MOSFETs on a substrate having pre-existing ridges of semiconductor material (i.e., a “corrugated substrate”), the resolution limitations associated with conventional semiconductor manufacturing processes can be overcome, and high-performance, low-power transistors can be reliably and repeatably produced. Forming a corrugated substrate prior to actual device formation allows the ridges on the corrugated substrate to be created using high precision techniques that are not ordinarily suitable for device production. MOSFETs that subsequently incorporate the high-precision ridges into their channel regions will typically exhibit much more precise and less variable performance than similar MOSFETs formed using optical lithography-based techniques that cannot provide the same degree of patterning accuracy. Additional performance enhancement techniques such as pulse-shaped doping and “wrapped” gates can be used in conjunction with the segmented channel regions to further enhance device performance.

An apparent network interface permits one processor such as a processor embedded within a larger processing system (an embedded processor) to communicate to a host processor or other processors and devices on the network to which the embedded processor is attached, using standard network communication mechanisms / protocols such as TCP / IP, NFS, FTP, HTTP, etc. The web server protocol HTTP is particularly useful because it permits the embedded computer to publish a user interface for remote monitoring and remote control using a standard web browser application. The invention provides the host computer with an apparent network interface that appears to be a standard network device, such as an Ethernet interface card. This apparent interface communicates directly with the embedded processor, which appears to be a device on this apparent network. Significant cost savings and performance enhancements are realized by implementing the communication directly over the host computer's peripheral bus rather than using standard network hardware such as Ethernet hardware.

A new Fast Recovery Plus (FR+) mechanism, and associated method, for wireless and / or mobile network applications to control data flow and avoid network congestion in a TCP / IP packet-switched network.

Methods, signals, devices, and systems are provided for using proxy servers to transparently forward messages between clients and origin servers if, and only if doing so does not violate network policies. In some systems, a transparent proxy uses a combination of standard-format HTTP commands, embedding auxiliary information in URLs and other tools and techniques to redirect an initial client request to one or more policy modules, such as a login server or an identity broker or an access control server. The policy module authenticates the request, and uses HTTP redirection to have the client transmit authorization data to the proxy. The proxy extracts the authorization data, directs the client to use a corresponding cookie, and subsequently provides the implicitly requested proxy services to the client in response to the client's subsequently providing the authorization data in a cookie. This is accomplished without requiring installation of any invention-specific software or hardware on either the client or the origin server, and also works with proxy servers that are known to the client. Unless the client request violates network policy, a person using the client will generally perceive no reduction of services, and will instead benefit from the proxy's caching and / or other performance enhancements.

A method and system for achieving stability while reallocating resources in a logically partitioned environment. The present invention comprises Performance Enhancement Program (PEP), Classification Program (CP), System Analysis Program (SAP), and System Evaluation Program (SEP). PEP allows a user to enter several performance parameters. CP classifies each of the virtual systems in the managed system based on their workload. SAP analyses the managed system to determine the configuration of the managed system. Managed systems configurations are classified according to the reciprocity of resource allocation and the overall symmetry of the managed systems. SEP evaluates the configuration of the managed system and recommends alterations for improved performance of the managed system. The managed system will be optimized when the functional differentiator (FD) of the virtual systems is small enough to allow reallocation of resources without an unacceptable sacrifice in managed system stability.

A system and method for optimizing a database query with improved performance enhancements is herein disclosed. The database query consists of one or more logical expressions. Through the repeated application of one or more rules, the logical expressions are transformed into execution plans. The query optimizer partitions the database query into one or more subproblems with each subproblem consisting of one or more logical expressions. A plan is obtained for each subproblem with the plan for the database query including the plans for each subproblem. The query optimizer is cost-based and uses rules including transformation and implementation rules that are used to perform transformations on the logical expressions in a subproblem in order to produce a plan. The rules are classified into context-free and context-sensitive in order to avoid generating duplicate expressions. Context-free rules are applied once for each logical expression and context-sensitive rules are applied once for each logical expression for a particular optimization goal. In a preferred embodiment, the query optimizer performs several optimization passes over the database query in order to obtain an optimal plan. For each pass, if no optimal plan exists for the requested optimization goal, existing plans having the same optimization goal are utilized with each input reoptimized for a more cost effective plan.

A plasma processing chamber having advanced coating for the showerhead and for an extended bottom electrode. The extended bottom electrode can be formed by one or more of the focus ring, cover ring, and plasma confinement ring. The extended electrode can be formed using a one-piece composite cover ring. The composite cover ring may be made of Al2O3 and include a Y2O3 plasma resistant coating. The plasma confinement ring may include a flow equalization ion shield that may also be provided with the plasma resistant coating. The plasma resistant coating of the extended electrode may have elements matching that of the showerhead.

Performance enhancement for signature based pattern matching may include one or more signature preprocessing steps. The signatures in the signature set may be preprocessed prior to performing pattern matching, including by breaking each signature broken down into one or more components. For at least one of the one or more components, boundary values as well as possible offsets of the boundary values may be identified and matched against a data stream to determine whether the data stream does not match a particular signature, thereby allowing a quick narrowing of the set of signatures to be applied fully to the data stream.
