accelerate. To speed up emulated execution of a TNS object file by applying the
Accelerator on TNS/R systems or the Object Code Accelerator (OCA) on TNS/E
systems before running the object file.
accelerated mode. See TNS accelerated mode.
accelerated object code. The MIPS RISC instructions (called the TNS/R region) that result
from processing a TNS object file with the Accelerator or the Itanium instructions
(called the TNS/E 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
either by the Accelerator with equivalent but faster MIPS RISC instructions (in the
TNS/R region) or the Object Code Accelerator (OCA) with equivalent but faster Itanium
instructions (in the TNS/E 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
TNS/R 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).
Accelerator-generated MIPS RISC instructions. See MIPS RISC instructions.
Accelerator-generated RISC instructions. See MIPS RISC instructions.
Accelerator mode. The TNS/R operational environment in which an object file containing
MIPS RISC instructions (called the TNS/R region) executes.
Contrast with TNS/R
native object code.
application program interface (API). A set of services (such as programming language
functions or procedures) that are called by an application program to communicate with
other software components. For example, under Open System Services, an application
uses functions defined by ISO/IEC IS 9945-1:1990 to perform process management,
time management, and file management functions through the operating system.
ASSIGN command. A TACL command that lets you associate a logical file name with a
Guardian file name (physical file name). The Guardian file name is a fully qualified file
ID. See also file name
and file ID.
Binder. A programming utility that combines one or more compilation units’ TNS object
code files to create an executable TNS object code file for a TNS program or library.
