Multisynth-based Architecture

Traditional clock generators use a simple integer-N phased-locked loop (PLL)-based architecture. The output clock frequency is a function of the input clock frequency and the PLL divider values as shown in the equation
Equation: fOUT = fIN.N/P.R
Traditional single PLL-based IC solutions are suitable for simple integer clock multiplication of reference inputs or clock generation from crystal inputs. However, many applications require clock generation of multiple non-integer-related frequencies (e.g., 125 MHz Ethernet and 106.25llMHz Fibre Channel). Traditional solutions require that the crystal frequency be changed to support each unique frequency plan. This forces the designer to use one or more custom crystals and multiple clock generator ICs to generate the required set of frequencies, increasing the cost, complexity and power consumption of the overall solution.

New Any-Rate Clock Multiplier Architecture Simplifies Design
Recent advances in mixed-signal analog design have made it possible to provide any-rate frequency synthesis from a single device. Silicon Labs newest clock architecture leverages a fractional-N PLL used in concert with a low-jitter fractional divider termed MultiSynth to produce any-rate frequency synthesis on multiple output clocks. The flagship of this new product family is the Si5338 Any-Rate, Any-Output Quad Clock Generator. This technology dramatically simplifies timing architectures by integrating the frequency synthesis capability of four PLLs in a single device, greatly reducing size and power requirements compared to traditional solutions.

MultiSynth Technology
The Si5338s low phase noise, high-frequency VCO supplies a high-frequency output clock to the MultiSynth block on each of the four independent output paths. The first stage of the MultiSynth architecture is a fractional-N divider, which switches seamlessly between the two closest integer divider values to produce the exact output clock frequency with 0 ppm error. To eliminate phase error generated by this process, the MultiSynth calculates the relative phase difference between the clock produced by the fractional-N divider and the desired output clock and dynamically adjusts the phase to match the ideal clock waveform. This novel approach makes it possible to generate any output clock frequency without sacrificing jitter performance. Based on this architecture, each output clock can be individually programmed to generate any frequency from 0.16 to 350 MHz, and select frequencies to 700 MHz. Typical jitter performance enabled by this MultiSynth-based architecture is 1 ps RMS.

The Architecture And Configuration Of J2me Application Development

J2ME or also know as Java ME is a platform that is specifically designed for application development to run on mobile phones, PDAs and other embedded systems. J2ME development features an adaptable user interface, which integrates with network protocols and extends support for mobile application development. The mobile applications that are developed on J2ME can be also migrated across various different mobile devices. J2ME application developers create a variety of different mobile applications based on the customized requirements of the clients. They are experience in creating diverse mobile solutions and hence most clients prefer to outsource their mobile business applications to India.

J2ME Architecture and configuration
J2ME comprises of configurations and profiles that allow a developer to customize it for the Java Runtime Environment (JRE). The configuration defines the JVM used and the profile adds domain-specific classes to define the application.

Configurations: The configuration uses a set of core classes and a specific JVM to define the basic run-time environment. The configurations are of two types where one is called CLDC for handheld devices and the second one is CDC for plug-in devices. CLDC is has been developed for 16-bit or 32-bit small computing devices that have limited memory. CDC requires a 32-bit architecture and has at least 2 MB of memory and implements a functional JVM.

Profiles: A profile comprises of classes that allow J2ME application developers to execute features that are typically available on a group of small computing devices. The profiles used with CLDC are mobile information device profile (MIDP) and PDA profile (PDAP). The profiles used with CDC include Foundation Profile, Game Profile, Personal Profile, Personal Basis Profile and RMI Profile.

J2ME Architecture
The J2ME architecture consists of five layers and they are as follows:

MIDP: This is the topmost layer and consists of Java APIs. J2ME application developers use these APIs to create network connections, storage, and user interface. It also provides access to CLDC libraries and MIDP libraries.
J2ME APIs: This is the profile that comprises of a minimum set of application programming interfaces required for the small computing devices.
Configurations: This is responsible to manage the interactions between the JVM and the profile.
Operating System: This is the bottom layer.

An Initial Introduction To Interior Architecture

Interior architecture can be seen as different from architecture in that the interior rooms, halls, doorways + stairs can be re designed once the initial design for the architecture of the building as a whole is in place. Interior architecture can be used to completely re design, for example a room such as a kitchen, bathroom in a family home which is quite common or a meeting room or office layout in a business environment or modify the existing design based on original architecture.

The interior architecture of a building can be changed for many reasons, either practical, where the interior of a building is going to be used for a new purpose or due to changing fashions or updated technologies. Examples of this are very common in many towns and cities where the exterior of a building is in a style of when it was built, say in the late 19th century but it’s interior has been completely re vamped incorporating modern design fashions and the latest technology.

The use of interior architecture means that for many buildings over a hundred years old the development of the look and design of their interior and exterior could often be the work of many different architects or teams of architects. This has meant for many of our towns and cities the architecture on view can be widely varied and reflect many different periods of time, design fashions and architecture styles. Some of which can be seen as timeless whilst others from certain eras can be seen as garish and bad taste 20 – 30 years down the line.

However no matter what a buildings exterior may look like with the help of interior architects, refurbishment and fit out specialists the interior look and feel of many buildings can be totally transformed with enough time and money bringing them up to date, that is until the latest style, fashion and technologies need integrating a few years down the line.

The main thing to differentiate architecture + interior architecture is that an architect is concerned with the concept of designing a new building the interior architect is concerned with the modification of existing buildings, some of which the design can be seen as timeless and look good for centuries whilst other will be an eye saw and look dated within 10 – 30 years.

This is quite a large and interesting topic, for further reading would advise looking at books + articles, online, in bookshops, news agents or in libraries on architecture, design + interior design.

Architecture Of Yesteryears

Shingle style architecture is an innovative form of Queen Anne and it was originated in America during the last two decades of 19th century.This name was given by Vincent Scully, a historian of building architecture.Among the various structures in America that are constructed in this style, The Hotel del Coronado in San Diego is considered as the biggest.The houses that are built in this style are horizontal structures built up on a stone laid foundation.The asymmetrical designs and irregular construction make the building process highly complicated and as a result the cost of construction was far beyond the affordable range for common people.Thus it was considered as a luxury homes design. The roofs are more complex in this type of architecture. Many of such houses have gabled roofs with a tower in the front. A few houses have roofs that are hipped. In the gambrel form of roofs, the third storey of the building will be hidden in the roof so that the building will appear as a two storeyed building. The roof shingles and wall shingles will be in different colors. Most of the houses have towers and if a building is without tower, a part of its wall will be bulged out.

This type of architecture has the provision for more numbers of big and small windows. The windows are mostly double-hung with a single sash below and multiple sashes above. For huge walls, the windows will be in 2, 3 or more rows and there are various designs for the windows. In the most complex designs, large windows are kept in bays with 1, 2 or 3 stories. The more stylish windows will be in square, rectangular or circular shapes.Entrance with spacious porch is characteristic of this architecture.People used to relax in the porches which are supported by balusters, columns or stone supports.

The modern houses that are built in Shingle style architecture offer a host of distinctive features including natural surroundings, energy efficiency and healthy indoor atmosphere. These houses demonstrate how wood, stone and sunlight can be utilized to provide a healthy shelter.There are many holiday homes that are built in this style of architecture. Many wealthy people have constructed this type of homes at famous resorts and also at sea-side plots. Natural colors, exterior covered by wooden shingles and an asymmetric structure are the basic features of this architectural form. The other common features are big porches, irregular roofs, towers, verandas, asymmetric floors, chimneys, huge staircases and fireplaces etc.

It is highly recommended from both a design and value standpoint when we were looking to home designs and build our dream home. For more information about Shingle style architecture please visit us.

Architecture A Brief Introduction and Marketing Tips

Architecture is an art and science that marries the building and design of structures. In some ways one can say that, along with engineering, it is the sign of civilization. Once man was able to settle down and fashion his own dwelling, even by primitive means, this was the start of the first civilizations.

Originally, these structures were purely functional serving to keep people safe from bad weather and wild animals, and to give them privacy. But as modern construction procedures were developed, along with more advanced materials, architecture and engineering began to take a more artistic leaning.

The earliest treatise on the subject, De Architectura, was written by Vitruvius, dates back to the 1st Century CE. In it, the Roman architect says that a building has to have form, function, and durability. To this day, most architects still conform to those three tenets. It is probably even safe to say that some are more successful at adhering to those dogmas than others.

A few examples of these people are Frank Lloyd Wright, a major proponent of organic architecture who is often touted to be the greatest American architect of all time (famous for the house called Fallingwater and for the Guggenheim Museum in New York City); I.M. Pei, a master of modern architecture who created the pyramid at the Louvre and the Bank of China Tower in Hong Kong; Frank Gehry, who designed the Dancing House in Prague; and the landscape architect and artist, Isamu Noguchi, among many others.

If these names sound familiar to you, it’s probably because their works are admired the world for being beautiful while being both functional and enduring. You’re likely to see their buildings mentioned in architectural texts, art books and even featured in architecture postcard designs. These, by the way, are not only proof of how respected the geniuses mentioned above are but, also function as a way to market their work. Like a portfolio, one might say.

In fact, some people in the business might publish high quality books that double as coffee table books and company profiles. Or, perhaps, they might have architecture postcard designs and construction postcard designs printed on elegant cards to send to potential clients. Others still, might support these efforts with their own websites.
