Original research date April 2011 Minimal InstructionSetComputer MISC is a Microprocessor processor architecture with a very small number of basic operations and corresponding opcode s. Such instructionset s are commonly stack based rather than register based to reduce the size of operand specifiers. Such a stack machine architecture is inherently simpler since all instructions operate on the top most stack entries. A result of this is a smaller instructionset, a smaller and faster instruction decode unit, and overall faster operation of individual instructions. The downside is that instructions tend to have more sequential dependencies, reducing instruction level parallelism . MISC architectures have much in common with the Forth programming language and the Java Virtual Machine . Probably the most commercially successful MISC was the INMOS transputer .

Overview NISC is a statically scheduled horizontal nanocoded architecture SSHNA . The term statically scheduled means that the operation scheduling and hazard handling are done by a compiler. The term horizontal nanocoded means that NISC does not have any predefined instructionset or microcode . The compiler generates nanocodes which directly control functional units, registers and multiplexers of a given datapath. Giving low level control to the compiler enables better utilization of datapath resources, which ultimately result in better performance.

An application specific instructionset processor ASIP is a component used in system on a chip design. The instructionset of an ASIP is tailored to benefit a specific application. This specialization of the core provides a tradeoff between the flexibility of a general purpose Central processing unit CPU and the performance of an ASIC . Some ASIPs have a configurable instructionset. Usually, these cores are divided into two parts static logic which defines a minimum ISA instructionset architecture and configurable logic which can be used to design new instructions. The configurable logic can be programmed either in the field in a similar fashion to an FPGA or during the chip synthesis.

Within the field of human computer interaction there has long been interest in developing adaptive automated instruction software to facilitate learning of application programs. This software would monitor a computer user s behavior while he or she uses the application program, and then provide optimized and personalized instruction to help the user become more skilled with the application. This form of instruction could be performed by a stand alone tutoring application, or it could be carried out by special routines built into the application program itself as with the Microsoft Office Assistant discussed below . Note that the history of adaptive learning approaches to education in general, some of which is summarized in the Wikipedia articles on spaced repetition and electronic learning , lies beyond the scope of this entry. Chronology of developments in the field A variety of different strategies for automated instruction in computer applications have been discussed and tried over a period of at least 25 years, although at present the technology does not appear to enjoy very wide application.

for the reduced product in algebraic topology James reduced product In model theory , a branch of mathematical logic , and in algebra , the reduced product is a construction that generalizes both direct product and ultraproduct . Let S sub i sub i &isin I be a family of structure mathematical logic structures of the same signature logic signature indexed by a set I , and let U be a filter mathematics filter on I . The domain of the reduced product is the quotient set quotient of the Cartesian product math prod i in I S i math by a certain equivalence relation two elements a sub i sub and b sub i sub of the Cartesian product are equivalent if math left i in I a i b i right in U , math If U only contains I as an element, the equivalence relation is trivial, and the reduced product is just the original Cartesian product. If U is an ultrafilter , the reduced product is an ultraproduct. Operations from are interpreted on the reduced product by applying the operation pointwise. Relations are interpreted by math R a 1 i sim , dots, a n i sim iff i in I mid R S i a 1 i, dots,a n i in U. , math For example, if each structure is a vector space , then the reduced product is a vector space with addition defined as a b sub i sub a sub i sub b sub i sub and multiplication by a scalar c as ca sub i sub c a sub i sub .

Thermodynamics cTopic List of thermodynamic properties System properties In thermodynamics , the reduced properties of a fluid are a set of state variables normalized by the fluid s state properties at its critical point . These dimensionless thermodynamic coordinates, taken together with a substance s compressibility factor , provide the basis for the simplest form of the theorem of corresponding states . ref name boles Reduced properties are also used to define the Equation of state Peng Robinson equation of state Peng Robinson equation of state , a model designed to provide reasonable accuracy near the critical point. ref cite journal title A New Two Constant Equation of State journal Industrial and Engineering Chemistry Fundamentals volume 15 year 1976 pages 59 64 author Peng, DY, and Robinson, DB doi 10.1021 i160057a011 ref They are also used to critical exponents , which describe the behaviour of physical quantities near continuous phase transitions. ref Hagen Kleinert and Verena Schulte Frohlinde, Critical Properties of sup 4 sup Theories , pp.8, http www.worldscibooks.com physics 4733.html World Scientific Singapore, 2001 ISBN 981 02 4658 7 Read online at http www.physik.fu berlin.de kleinert b8 ref Reduced pressure The reduced pressure is defined as its actual pressure math p math divided by its critical pressure math p c math ref name boles Cite book last1 Cengel first1 Yunus A. last2 Boles first2 Michael A. title Thermodynamics an engineering approach year 2002 publisher McGraw Hill location Boston isbn 0 07 121688 X pages 91 93 ref math p r p over p c math Reduced temperature The reduced temperature of a fluid is its actual temperature, divided by its critical ... are expressed in absolute temperature scales either Kelvin or Rankine scale Rankine .
