Glossary-14
A Virtual Address produced by the ARM processor can be changed by the current
Process ID to provide a Modified Virtual Address (MVA) for the MMUs and caches.
See also Fast Context Switch Extension.
One of two mutually exclusive debug modes. In Monitor debug-mode the processor
enables a software abort handler provided by the debug monitor or operating system
debug task. When a breakpoint or watchpoint is encountered, this enables vital system
interrupts to continue to be serviced while normal program execution is suspended.
See also Halt mode.
See Memory Protection Unit.
A JTAG-based tool for debugging embedded systems.
See Modified Virtual Address.
See Noncachable Buffered.
See Noncachable Nonbufferable.
Is a memory region where reads are performed from main memory and are not allocated
to the cache. Writes are performed to main memory through a write buffer, so processor
core execution can continue while the write is completed to main memory.
Is a memory region where reads are performed from main memory and are not allocated
to the cache. Writes are performed to main memory without buffering, so processor core
execution is halted while the write is completed.
See Physical Address.
The number of cycles in which no useful Execute stage pipeline activity can occur
because an instruction flow is different from that assumed or predicted.
See Cold reset.
In pipelined processors, the process of fetching instructions from memory to fill up the
pipeline before the preceding instructions have finished executing. Prefetching an
instruction does not mean that the instruction has to be executed.
An indication from a memory system to a core that it must halt execution of an
attempted illegal memory access. A Prefetch Abort can be caused by the external or
internal memory system as a result of attempting to access invalid instruction memory.
See also Data Abort, External Abort and Abort.
