Prefetch

Prefetch
The ability of a microprocessor to fetch additional opcodes and
operands before the current instruction is finished executing.
Prestore
The storage of states captured by the analyzer that precede states which
are normally stored. If the normal storage qualifier specifies the entry
address of a function or routine, prestore can be used to identify the
callers of that function or routine.
Prestore Qualifier
A specification that must be met by a state before it can be saved in the
analyzer prestore memory.
Primary Sequencer Branch
Occurs when the analyzer finds the primary branch state specified at a
certain level and begins searching for the states specified at the primary
branch's destination level.
Qualifier
A specification that must be met before an action can be taken by the
analyzer. For example, a store qualifier is a specification that must be
met by an incoming state before it can be stored in the trace memory.
The "arm" condition can be used as an additional qualifier. For
example, an external analyzer may be set up to supply a true signal to
the rear panel BNC connector on the card cage when it detects a true
condition in the target system. Then the analyzer can be set up to store
qualify a certain kind of state, but only when the arm signal from the
BNC is true.
Real-Time Execution
Continuous execution of the user program without interference from
the emulator. (Such interference occurs when the emulator temporarily
breaks into the monitor so that it can access register contents or target
system memory or I/O.)
