branch prediction

Branch prediction can be thought of as a two step process.

One alternative to this would be to use branch prediction.

The R5000 did not perform dynamic branch prediction for cost reasons.

They differ in the hints provided to the branch prediction hardware.

These bits are used to cache branch prediction information associated with those instructions.

Branch prediction attempts to guess whether a conditional jump will be taken or not.

Branch prediction is performed by logic in the I-box during stage two.

Branch prediction also takes place at this stage.

Improved branch prediction: Uses eight predictors in two pipeline stages.

There are two such instructions, and they differ only in the hints provided for the branch prediction hardware.

The e5500 also introduces an enhanced branch prediction unit with an 8-entry link stack.

When branch prediction works, the microprocessor completes instructions more efficiently.

The B4900 branch prediction history state was stored back into the in-memory instructions during program execution.

The PA-8000 performs branch prediction using static or dynamic methods.

Branch prediction which is used to avoid stalling for control dependencies to be resolved.

Scott McFarling proposed combined branch prediction in his 1993 paper.

This is where branch prediction comes in.

The most common solution for this type of problem is to use a type of branch prediction.

With loops, branch prediction becomes unnecessary - one instance of a particular loop should execute the same way as every other.

It has a hardware prefetch unit and a three way branch prediction unit.

Additional implementation changes for higher performance include a faster adder, and more extensive branch prediction logic.

Branch target prediction is not the same as branch prediction.

Static branch prediction is employed to minimize the cost of branch instructions.

The SA-110 did not have branch prediction hardware, but had mechanisms for their speedy processing.

To further improve the performance the core utilized branch prediction and a number of techniques to resolve data dependency conflicts.
