Architecture. A detailed specification of requirements for a processor or
Autovector. A method of determining the starting address of the service
Branch folding. The replacement with target instructions of a branch
Branch prediction.The process of guessing whether a branch will be taken.
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.
instruction and any instructions along the not-taken path when a
branch is either taken or predicted as taken.
Such predictions can be correct or incorrect; the term ‘predicted’ as
it is used here does not imply that the prediction is correct
(successful). Branch resolution.The determination of whether a
branch is taken or not 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
