accelerate. To use the Accelerator program to generate an accelerated object file.
accelerated object code. The RISC instructions that result from processing a TNS object
file with the Accelerator.
accelerated object file. The object file that results from processing a TNS object file with
the Accelerator. An accelerated object file contains the original TNS object code, the
accelerated object code and related address map tables, and any Binder and symbol
information from the original TNS object file.
Accelerator. A program that processes a TNS object file and produces an accelerated
object file. Most TNS object code that has been accelerated runs faster on TNS/R
processors than TNS object code that has not been accelerated.
ancestor. The process that is notified when a named process or process pair is deleted.
It is the process that created the named process or process pair.
application. One or more processes that achieve a specific objective. Multiple processes
in an application often communicate with each other using the message system and
file system. See also “program” and “process.”
C-series-compatible interface. The set of procedure calls, system messages, and event-
message tokens available on a D-series system that permits unconverted applications
to execute.
C-series process file name. A 12-word internal-format file name that identifies a process
either by name or by CPU, PIN on a C-series system or on a D-series system using the
C-series-compatible interface.
C-series system. A system that is running a C-series version of the operating system.
CISC. See “complex instruction-set computing (CISC).”
complex instruction-set computing (CISC). A processor architecture based on a large
instruction set, characterized by numerous addressing modes, multicycle machine
instructions, and many special-purpose instructions. Contrast with “reduced
instruction-set computing (RISC).”
converted application. In the context of operating system releases, an application that
has been modified to use extended features of the D-series operating system (for
example, to run at a high PIN).
CPU, PIN. A C-series process identifier that is an 8-bit CPU number and an 8-bit
process number. It is sometimes called a PID.
creation process ID (CRTPID). See “process ID.”
creator. The process that initiates the execution of another process. Compare with
“mom” and “ancestor.”
CRTPID. See “process ID.”
D-series enhanced interface. The set of procedure calls, system messages, and event-
message tokens available on a D-series system that enable an application to take
