Arithmetic Logic Unit (ALU) is the main component in the processors. Most important design consideration in integrated circuit is power. In all the components of ALU data path is the active one and it consumes more percent of power in the total power. In the modern microprocessors it is important to have power efficient data paths. To reduce the power consumption in microprocessors the ALU is designed using PNS-FCR static CMOS logic. In this paper static CMOS logic is used to reduce power consumption. Static technique does not need any clock. So it leads to less power consumption. For the implementation of the ALU with the PNS-FCR static logic mentor graphics tool is used. The power consumption of ALU is compared with and without using FCR. An 8-bit ALU is designed in mentor graphics with 130nm technology. The proposed design methodology gives less power consumption

This paper shows not only that the state of an objecty parameterizes the dyad (stimulus, response) but that it is also the performer of the state transition initiated by the stimulus. Thus, the logic object is a feedback composition of the logic pseudoobject and the static logic object. It is also stated that, without considering the new role of the state, the content of the concept "state" cannot be completely explained. The current intuitive conception of canonical decomposition of an entity is confronted with the exactly introduced decomposition and with the mentioned division of the logic object into a pseudoobject and a static object.

Logic models are commonly used by evaluators to illustrate relationships among a program's inputs, activities, outputs, and outcomes. They are useful in helping intended users develop programs, communicate a program's theory of change, and design evaluations. However, as static documents, logic models can be challenging to build, work with, and present to stakeholders, especially for large and complex programs. Challenged by this inadequacy of static logic models, a program evaluator turned to a graphic designer and a software developer for help. Together, this interdisciplinary group developed web-based software (Dylomo) that allows evaluators to create logic models that better communicate the logic within the model. In this paper, we describe the process by which this interdisciplinary group created this new technology—including a user-testing experience at the Canadian Evaluation Society Conference in Canada in June 2016—to build and present logic models that use interactivity and allow program evaluators to more easily demonstrate the logic within a complex program and to visually explore the potential effects of changes within the program's landscape. This software is freely available on the web, so readers can apply it to their own evaluation practice.
