By Florin Balasa, Dhiraj K. Pradhan

Energy-Aware reminiscence administration for Embedded Multimedia platforms: A Computer-Aided layout Approach offers contemporary computer-aided layout (CAD) rules that handle reminiscence administration initiatives, quite the optimization of power intake within the reminiscence subsystem. It explains the right way to successfully enforce CAD ideas, together with theoretical tools and novel algorithms.

The ebook covers a variety of energy-aware layout suggestions, together with data-dependence research suggestions, reminiscence measurement estimation tools, extensions of mapping ways, and reminiscence banking ways. It indicates how those strategies are used to judge the information garage of an software, lessen dynamic and static strength intake, layout energy-efficient tackle iteration devices, and lots more and plenty more.

Providing an algebraic framework for reminiscence administration initiatives, this publication illustrates tips on how to optimize strength intake in reminiscence subsystems utilizing CAD suggestions. The algorithmic kind of the textual content may also help digital layout automation (EDA) researchers and power builders create prototype software program instruments for system-level exploration, with the objective to finally receive an optimized architectural answer of the reminiscence subsystem.

Logic-Based Artificial Intelligence (The Kluwer International Series in Engineering and Computer Science Volume 597)

This landmark quantity represents the end result of over forty years of study within the use of good judgment as a foundation for representing and manipulating difficulties within the box of man-made intelligence. The use of good judgment as a foundation for common-sense reasoning was once all started via John McCarthy in 1959. the gathering comprises either unique study and surveys of just about each topic that makes use of common sense in AI, contributed via best scientists, and grew out of initial paintings provided at the Workshop on Logic-Based synthetic Intelligence held in Washington, DC, June 1999.

Example text

A dependence is called a uniform dependence if it is of the form z → z + b, where b is a constant vector. It is called an affine dependence if it is of the form z → Az + b, where A is a constant matrix and b is a constant vector. Uniform dependences are also affine dependences with A being the identity matrix. 3 (Uniform and Affine Recurrence Equations) A recurrence equation of the form defined above is called a uniform recurrence equation (URE) if all of the dependency functions Ii are of the form I(z) = z + b, where b is a constant vector.

4 All rays are saturated by the positivity constraint, and no vertex is saturated by the positivity constraint. 10. The following property gives a rule for when the positivity constraint will be needed. 5 The positivity constraint will be irredundant if the size of the set of rays is ≥ d, the dimension of the ray space, and the rank of the ray set is d. Positivity constraints are included so polyhedra can have valid dual form representations (according to Prop. 1 and Prop. 2). The positivity constraint is kept in polyhedra where it is needed (according to Prop.

The lineality space of a polyhedron is unique, although it may be represented using any appropriate basis that is set of m linearly independent lines. A set K is called a flat if it has the property: x, y ∈ K implies all affine combinations of x, y are also in K. The dimension of a flat is the rank of a set of lines that span the flat. A flat of dimension d is called an d-flat. A 0-flat, 1-flat, and 2-flat are called respectively a point, line, and plane. Flats are containers that contain polyhedra. 2 Decomposition In 1936, Motzkin gave the decomposition theorem for polyhedra.
