C/C++ Run-Time Model and
Environment
This section provides a full description of the ADSP-219x DSP run-time
model and run-time environment. The run-time model, which applies to
compiler-generated code, includes descriptions of the layout of the stack,
data access, and call/entry sequence. The C/C++ run-time environment
includes the conventions that C/C++ routines must follow to run on
ADSP-219x DSPs. Assembly routines linked to C/C++ routines must fol-
low these conventions.
ADI recommends that assembly programmers maintain stack
conventions.
