accelerate. To speed up emulated execution of a TNS object file by applying the
Accelerator for TNS/R system execution or the TNS Object Code Accelerator (OCA)
for TNS/E system execution before running the object file.
accelerated mode. See TNS accelerated mode.
accelerated object code. The MIPS RISC instructions (in the MIPS region) that result from
processing a TNS object file with the Accelerator or the Intel® Itanium® instructions (in
the Itanium instruction region) that result from processing a TNS object file with the
Object Code Accelerator (OCA).
accelerated object file. A TNS object file that, in addition to its TNS instructions (in the
TNS region) and symbol information (in the symbol region), has been augmented by
the Accelerator with equivalent but faster MIPS RISC instructions (in the MIPS region),
the Object Code Accelerator (OCA) with equivalent but faster Intel® Itanium®
instructions (in the Itanium instruction region), or both.
Accelerator. A program optimization tool that processes a TNS object file and produces an
accelerated object file that also contains equivalent MIPS RISC instructions (called the
MIPS region ). TNS object code that is accelerated runs faster on TNS/R processors
than TNS object code that is not accelerated. See also TNS Object Code Accelerator
(OCA).
actual parameter. An argument that a calling procedure or subprocedure passes to a called
procedure or subprocedure. Compare to formal parameter.
addressing mode. The mode in which a variable is to be accessed—direct addressing or
extended addressing—as specified in the data declaration.
aligned. In native mode, a data item is aligned if its address is a multiple of its size; for
example, a 4-byte data item is aligned if its byte address is a multiple of four.
arithmetic expression. An expression that computes a single numeric value.
array. A variable that represents a collectively stored set of elements of the same data type
that are uniquely identified by a monotonically increasing integer with a user-specified
base integer.
assignment expression. An expression that stores a value in a variable.
assignment statement. A statement that stores a value in a variable.
ASSIGN command. An HP TACL command (available only on Guardian platforms) that lets
you associate a logical file name with an HP file name.
