nonexact point
nonexact point. A code location within an accelerated object file that is between memory-
exact points. The mapping between the TNS program counter and corresponding
RISC instructions is only approximate at nonexact points, and interim changes to
memory might have been completed out of order. Breakpoints cannot be applied at
nonexact points. Contrast with memory-exact point and register-exact point.
noninteractive mode. A mode of operation that usually involves a command file (an EDIT
file that contains a series of commands). Contrast with interactive mode.
NonStop™ Kernel operating system. See HP NonStop™ operating system.
NonStop™ Series TNS. See TNS.
NonStop™ Series TNS/E. See TNS/E.
NonStop™ Series TNS/R. See TNS/R.
NonStop Technical Library. See HP NonStop™ Technical Library (NTL).
NSAA. HP NonStop™ advanced architecture.
NSE-A processor. See HP NonStop™ System EPIC Model A processor (NSE-A
processor).
OBEY file. See compiler extended-data segment.
object code accelerator (OCA). See TNS Object Code Accelerator (OCA).
object code interpreter (OCI). See TNS Object Code Interpreter (OCI).
OCA. (1) The command used to invoke the TNS Object Code Accelerator (OCA) on a
TNS/E system. (2) See TNS Object Code Accelerator (OCA).
OCA region loading. A task performed when necessary by the TNS emulation software for
TNS/E machines. This task involves mapping into memory the Intel® Itanium®
instructions and any tables needed at run time from the TNS Object Code Accelerator
(OCA) region (called the Itanium instruction region) of an OCA-generated object file.
OCA region of an object file. The region of a TNS Object Code Accelerator (OCA)-
generated object file, also called the Intel® Itanium® instruction region, that contains
Itanium instructions and tables necessary to execute the object file on a TNS/E system
in TNS accelerated mode. The TNS Object Code Accelerator (OCA) creates this
region. See also OCA-accelerated object code. Contrast with Accelerator region of an
object file.
OCA-accelerated object code. The Intel® Itanium® instructions that result from processing
a TNS object file with the TNS Object Code Accelerator (OCA).
OCA-accelerated object file. A TNS object file that has been augmented by the TNS
Object Code Accelerator (OCA) with equivalent but faster Intel® Itanium® instructions.
