Design Patterns


A pattern is a proven solution to a problem in a context.
Christopher Alexander says each pattern is a three-part rule which expresses a relation between a certain context, a problem, and a solution.
Design patterns represent a solutions to problems that arise when developing software within a particular context.
i.e Patterns = problems.solution pairs in a context

Two-dimensional filters are usually part of the implementation of digital image processing applications. These filters process recursive sets of instructions and require high computational speed. Optimized implementations of these filters depend on the use of Application Specific Integrated Circuits (ASICs). A system with multiple parallel processing units is a feasible design option able to achieve the required computational performance. In this paper, a loop transformation algorithm, which allows the efficient utilization of a parallel multip ....etc

Formal methods have been advocated as one of those techniques that can produce highquality software and hardware systems that has been demonstrated to come in ontime, within budget, and satisfy procurer requirements. They are, however, perceived to be difficult to use and unsuitable for presentation to nonspecialists. In addition, they have been criticized for paying too little attention to the system development process.

Traditional structured (bubblesandarrows) methods, however, do excel at supporting the development process, but do not ....etc

Common Emitter BJT Amplifier Design Current Mirror Design


Some Random Observations
● Conditions for stabilized voltage source biasing
● Emitter resistance, RE, is needed.
● Base voltage source will have finite resistance, RB.
● needs to be much larger than RB.
● Small RB - relative to RS - will attenuate input signal.
● Larger RE permits larger RB, but results in lower gain.
● Gain = -RC/RE for RE >> re.
● Split RE with bypassing increa ....etc

In order to conserve natural resources and economize energy, weight reduction has been the main focus of automobile manufacturers in the present scenario. Weight reduction can be achieved primarily by the introduction of better material, design optimization and better manufacturing processes. The suspension leaf spring is one of the potential items for weight reduction in automobiles as it accounts for 10% - 20% of the unsprung weight. This achieves the vehicle with more fuel efficiency and improved riding qualities.

ABSTRACT
Many system-on-chip (SoC) integrated circuits contain embedded cores with different scan frequencies. To better meet the test requirements for such heterogeneous SoCs, leading tester companies have recently introduced port-scalable testers, and Many IP core design software like Xilinx, Leonardo Spectrum, and Modelsim etc which can used to design ip core like DMA ,Interrupt Controller etc .These Ip core can be Power aware an Implement on soc by choosing different design tech ....etc

Success is all about being in the right place at the right time ?.. and the axiom is a guiding principle for designers of motorsport circuits. To avoid problems you need know where and when things are likely to go wrong before cars turn a wheel -and anticipating accidents is a science.

Take barriers, for example .there is little point erecting them in the wrong place -but predicting the right place is a black art. The FIA has developed bespoke software, the Circuit and Safety Analysis System (CSAS), to predict problemareas on F ....etc
