Debugger
A debugging system that includes a program, used to detect, locate, and correct software faults,
together with custom hardware that supports software debugging.
Direct Memory Access (DMA)
An operation that accesses main memory directly, without the processor performing any
accesses to the data concerned.
Doubleword
A 64-bit data item. The contents are taken as being an unsigned integer unless otherwise
stated.
Doubleword-aligned
A data item having a memory address that is divisible by eight.
Endianness
Byte ordering. The scheme that determines the order that successive bytes of a data word are
stored in memory. An aspect of the system’s memory mapping.
See also
Exception
An event that interrupts program execution. When an exception occurs, the processor suspends
the normal program flow and starts execution at the address indicated by the corresponding
exception vector. The indicated address contains the first instruction of the handler for the
exception.
An exception can be an interrupt request, a fault, or a software-generated system exception.
Faults include attempting an invalid memory access, attempting to execute an instruction in an
invalid processor state, and attempting to execute an undefined instruction.
Exception service routine
See
Exception vector
See
Flat address mapping
A system of organizing memory in which each physical address in the memory space is the
same as the corresponding virtual address.
Halfword
A 16-bit data item.
Illegal instruction
An instruction that is architecturally Undefined.
Implementation-defined
The behavior is not architecturally defined, but is defined and documented by individual
implementations.
Implementation-specific

“Interrupt vector”
“Little-endian (LE)”
