Architecture. A detailed specification of requirements for a processor or

Branch prediction.The process of guessing whether a branch will be taken.
Branch resolution.The determination of whether a branch is taken or not
Burst. A multiple-beat data transfer.
Cache. High-speed memory containing recently accessed data and/or
Cache coherency. An attribute wherein an accurate and common view of
computer system. It does not specify details of how the processor or
computer system must be implemented; instead it provides a
template for a family of compatible implementations.
routine by fetching the value from a lookup table internal to the
processor instead of requesting the value from the system.
Such predictions can be correct or incorrect; the term ‘predicted’ as
it is used here does not imply that the prediction is correct
(successful).
taken. A branch is said to be resolved when the processor can
determine which instruction path to take. If the branch is resolved as
predicted, the instructions following the predicted branch that may
have been speculatively executed can complete (see completion). If
the branch is not resolved as predicted, instructions on the
mispredicted path, and any results of speculative execution, are
purged from the pipeline and fetching continues from the
nonpredicted path.
instructions (subset of main memory).
memory is provided to all devices that share the same memory
system. Caches are coherent if a processor performing a read from
