Methods and systems for selectively processing VLAN traffic from different networks while allowing flexible VLAN identifier assignment are disclosed. According to one aspect, a layer 2 switch includes a virtual switch identifier data structure that associates a VLAN identifier extracted from a layer 2 frame and a port identifier corresponding to a port on which a frame is received with a virtual switch identifier. The virtual switch identifier is used to select a per-virtual-switch data structure, such as a forwarding table. The per-virtual-switch data structure is used to control processing of the layer 2 frame on a per-virtual-switch basis. The per-virtual-switch data structure may also be updated separately from the data structures assigned to other virtual switches.

A method of wireless transmission of an email having a content in a language unsupported in a mobile communication system by Multimedia Messaging Service (MMS) to a recipient using a mobile phone. An email server receives the email and extracts from the email text information indicative of the recipient and relating to content. A conversion server, connected to the email server, converts the content information from text into an image and composes a MMS message including the image. A MMS message transmitter, connected to the conversion server, transmits the MMS message to the mobile phone. Multi-language (supported and unsupported languages) wireless email transmission is thus made possible.

The APIs provide a mechanism for a computer application to interface with various components and modules of an operating system for a resource-limited environment. The APIs further provide a mechanism to interface with input/output devices commonly found in embedded systems running in a resource-limited environment.

The invention discloses an integration method for large memory pages based on bitmap alteration of memory pages. The method comprises following steps: acquiring page fault frequency of a system memory according to the preset period when page fault frequency is larger than a first threshold value; obtaining access information of all memory pages in the period and calculating access heat rate of all the memory pages based on access information of all the memory pages; and renewing a bitmap of a system according to access heat rate of all the memory pages, calculating the digit number of difference before and after renewal of the bitmap, and splitting large pages or merging small pages to the system memory when the digit number of difference is larger than a second threshold value according to a renewed bitmap.The integration method for large memory pages based on bitmap alteration of memory pages has following beneficial effects: based on access heat rate of all the memory pages in the system memory, splitting of large pages or merging of small pages are carried out in order to match an allocation scheme with a practical situation of the system memory; flexibility in use and access speed of the system memory are improved; and final integration operation is performed or not based on threshold values for page fault frequency and the digit number of the bitmap so that bumping effect possibly caused by fluctuation of load is reduced.

A method of controlling a polishing operation is described. A controller stores an optical model for a layer stack having a plurality of layers and a plurality of input parameters including a first parameter and a second parameter. The controller stores data defining a plurality of default values for the first parameter and measures an optical property of a substrate and generates a second value. Using the optical model and the second value and iterating over the first values, a number of reference spectra are calculated. A spectrum is measured and the measured spectrum is matched to the reference spectra and the best matched reference spectrum is determined. The first value of the best matched reference spectrum is determined and is used to adjust a polishing endpoint or a polishing parameter of a polishing apparatus.

A type of portable computer with interchangeable components is provided. The chassis of the portable computer includes an upper part, a lower part, and an edge part. The edge part can be equipped with removable input and output (I/O) plates. The motherboards and batteries of this type of portable computer are standardized with or without optional components such as optical drives and/or 2.5 inch hard drives. Motherboards, batteries and other components can be mounted in the chassis of the portable computer through fixed mounting stands and/or removable mounting standoffs. The portable computer allows the I/O plates and/or the edge part to be replaced. Therefore, a motherboard with different I/Os, a motherboard and other components with different heights, and an auxiliary cooling system can be installed in the chassis. In the portable computer, mounting stands and standoffs can be shared by multiple components.

The present invention is related with the management of memory in environments of limited resources, such as those found for example in a smart card. In a more particular manner, the invention relates to a method of managing the data storage resources of volatile memory, the object of which is to reduce the size of volatile memory necessary to implement the stack of the system, and thereby to reserve more volatile memory available for other needs or procedures of the system or of other applications When the stack grows and comes close to its established limit, the system carries out a transfer of a stack block located in the volatile memory to an area of non-volatile memory, hence this transfer allows a compression of the stack increasing its size in a virtual manner.

Disclosed are an apparatus and method of operating and allocating a shared memory between various applications operating via a processing computing platform. One example may include receiving a first buffer context switch request message from a first application operating via a processor, transmitting a first buffer context switch flag to the processor operating the application confirming the first buffer context switch request was received, receiving a second buffer context switch request from a second application with a different processing cycle operating via the processor and transmitting a second buffer context switch flag to the processor operating the second application confirming the second buffer context switch request was received. Once the applications have been identified and confirmed, a synchronization operation may be performed to create a shared number of memory units between at least two different buffers and provide the shared memory units to the first application and the second application.
