9.2
Here methods for embedding programs into systems employing the H8SX, AE5, H8S/2600,
H8S/2000, H8/300H and H8/300 are explained.
In addition, when using I/O and other C/C++ library functions, the library must be initialized
during preparation of the execution environment. In particular, when using I/O (stdio.h, ios,
streambuf, istream, ostream) and memory allocation (stdlib.h, new), low-level I/O routines and
memory allocation routines must be created.
When using C library functions for program termination (the exit, atexit, abort functions), these
functions must be created separately according to the user system.
In section 9.2.1, the method used to determine addresses for program memory is explained, and
actual examples are used to describe the method for specifying options in the optimizing linkage
editor for determining addresses.
In section 9.2.2, execution environment settings are explained, and an actual example of a program
to set the execution environment is described.
Library function initialization processing, creation of low-level routines, and examples of creation
of functions for termination processing are also explained.
9.2.1
the program must be determined, and these memory areas must be allocated to appropriate
memory addresses.
execution instructions corresponding to functions in the program and data declared using external
data definitions, and areas which are dynamically allocated, such as the stack area. Below,
methods for allocation of each type of area are explained.
To embed a program in a system, the following preparations are necessary.
In order to embed an object program into a system, the size of the memory areas to be used by
Memory areas used by a program include areas which are statically allocated, such as for
Memory allocation
Each section, the stack area, and the heap area must be allocated to system ROM and RAM.
Settings for the program execution environment
Processing to set the program execution environment includes register initialization, memory
initialization, and program startup.
