TNS accelerated mode

TNS accelerated mode. A TNS emulation environment on a TNS/R or TNS/E system in

which accelerated TNS object files are run. TNS instructions have been previously

translated into optimized sequences of MIPS or Intel Itanium instructions. TNS

accelerated mode runs much faster than TNS interpreted mode. Accelerated or

interpreted TNS object code cannot be mixed with or called by native mode object

code. See also Accelerator

and TNS Object Code Accelerator (OCA). Contrast with

TNS interpreted mode

, TNS/R native mode and TNS/E native mode.

TNS C compiler. The C compiler that generates TNS object files. Contrast with TNS/R

native C compiler and TNS/E native C compiler.

TNS code segment. One of up to 32 128-kilobyte areas of TNS object code within a TNS

code space. Each segment contains the TNS instructions for up to 510 complete

routines. Each TNS code segment contains its own procedure entry-point (PEP) table

and external entry-point (XEP) table. It can also contain read-only data.

TNS code segment identifier. A seven-bit value in which the most significant two bits

encode a code space (user code, user library, system code, or system library) and the

five remaining bits encode a code segment index in the range 0 through 31.

TNS code segment index. A value in the range 0 through 31 that indexes a code segment

within the current user code, user library, system code, or system library space. This

value can be encoded in five bits.

TNS code space. One of four addressable collections of TNS object code in a TNS

process. They are User Code (UC), User Library (UL), System Code (SC), and System

Library (SL). UC and UL exist on a per-process basis. SC and SL exist on a per-node

basis.

TNS compiler. A compiler in the TNS development environment that generates 16-bit TNS

object code following the TNS conventions for memory, stacks, 16-bit registers, and

call linkage. The TNS C compiler is an example of such a compiler. Contrast with

TNS/R native compiler

and TNS/E native compiler.

TNS Emulation Library. A public dynamic-link library (DLL) on a TNS/E system containing

the TNS object code interpreter, millicode routines used only by accelerated mode, and

millicode for switching among interpreted, accelerated, and native execution modes.
