In computer science, predication is an architectural feature that provides an alternative to conditional transfer of control, as implemented by conditional branch machine instructions.

What is predication in computer science?

In computer science, predication is an architectural feature that provides an alternative to conditional transfer of control, as implemented by conditional branch machine instructions.

What is meant by branch prediction?

Branch prediction attempts to guess whether a conditional jump will be taken or not. Branch target prediction attempts to guess the target of a taken conditional or unconditional jump before it is computed by decoding and executing the instruction itself.

Why is branch prediction important?

Branch prediction is a technique used in CPU design that attempts to guess the outcome of a conditional operation and prepare for the most likely result. A digital circuit that performs this operation is known as a branch predictor. It is an important component of modern CPU architectures, such as the x86.

What is branch prediction buffer in computer architecture?

Branch prediction is an approach to computer architecture that attempts to mitigate the costs of branching. Branch predication speeds up the processing of branch instructions with CPUs using pipelining. The technique involves only executing certain instructions if certain predicates are true.

What is predication linguistics?

Summary. Predication is typically thought of as a (linguistic) semantic notion: the construction of a proposition from two components, a subject and a predicate. This chapter attempts to outline the main ways in which predication has been analyzed in the generative syntactic literature.

What are predicates used in?

The predicate is used to tell the reader what the subject does. It contains a verb and shows action.

What is branch prediction and speculative execution?

Branch prediction is done by the processor to try to determine where the execution will continue after a conditional jump, so that it can read the next instruction(s) from memory. Speculative execution goes one step further and determines what the result would be from executing the next instruction(s).

What is meant by dynamic branch prediction?

This says whether the branch was recently taken or not. Based on this, the processor fetches the next instruction from the target address / sequential address. If the prediction is wrong, flush the pipeline and also flip prediction. So, every time a wrong prediction is made, the prediction bit is flipped.

Where does branch prediction happen?

This is done in a special part of the processor called the branch predictor unit (BPU). The branch predictor attempts to figure out a destination of a branching instruction very early and with very little context. This magic happens before the “decoder” pipeline stage and the predictor has very limited data available.

What are the types of branch prediction?

Branch prediction schemes are of two types: static branch schemes and dynamic branch schemes. branch scheme (hardware techniques) is based on the hardware and it assembles the information during the run-time of the program.

What is branch prediction list different types of branch prediction?

Types of Branch Prediction Technique – Branch prediction technique can be of two types: Static Branch Prediction Technique. Dynamic Branch Prediction Technique.

What is predication in syntax?

Predication is typically thought of as a (linguistic) semantic notion: the construction of a proposition from two components, a subject and a predicate. Syntactically, this corresponds to the idea that a clause – or any other structure that will be interpreted as a proposition – has an essentially bipartite structure.

What is predicative predication?

Predication in philosophy refers to an act of judgement where one term is subsumed under another. A comprehensive conceptualization describes it as the understanding of the relation expressed by a predicative structure primordially (i.e. both originally and primarily) through the opposition between particular and general or the one and the many.

What is predication According to Aristotle?

It was Aristotle who posited that the division between subject and predicate is fundamental and that there is no truth unless a property is “predicated of” something. In Plato ‘s works, predication is demonstrated in the analysis of desire.

What is predication According to Kahn?

In describing Greek philosophy, Charles Kahn identified predication as one of the three concepts – along with truth and reality – that ontology connected. It is suggested that predication is equivalent to the German concept of Aussage.

What is the difference between ontological and logical predication?

There are scholars who note that Aristotle’s thought on the subject can be distinguished in two levels: ontological (where predicates pertain to things); and, logical (where predicates are something that is said of things). Like Plato, Aristotle used predication to address the Problem of Universals.
