SPI
SPI. See Subsystem Programmatic Interface (SPI).
SPI token. The smallest accessible unit in an SPI message; each token has a value and a
code that identifies the value. See also simple token and extensible structured token.
SPI token code. The identifying code of a simple token.
SPI token map. The identifying code of an extensible structured token.
SPI token type. The data type and size of one or more tokens.
Subsystem Programmatic Interface (SPI). A set of procedures and associated definition
files and a standard message protocol used to define common message-based
interfaces for communication between management applications and subsystems. It
includes procedures to build and decode specially formatted messages; definition files
in TAL, COBOL, and HP Tandem Advanced Command Language (TACL) for inclusion
in programs, macros, and routines using the interface procedures; and definition files in
Data Definition Language (DDL) for programmers writing their own subsystems.
TNS architecture. NonStop Series architecture. HP computers that are based on complex
instruction set computing (CISC) technology. TNS architecture implements the TNS
instruction set.
TNS/E architecture. NonStop Series/Itanium® architecture. HP computers that are based
on Itanium technology. TNS/E architecture implements the Itanium instruction set
[explicitly parallel instruction set computing (EPIC)] and are upwardly compatible with
the TNS and TNS/R architectures.
TNS/R architecture. NonStop Series/RISC architecture. HP computers that are based on
reduced instruction set computing (RISC) technology. TNS/R architecture implements
the RISC instruction set and are upwardly compatible with the TNS architecture.
