When allocating memory as shown in figure 9.4, the following subcommands are specified at link
time.
Explanation [1] Space for section R of size equal to that of section D is secured in the output
Explanation [2] Sections P, C and D are allocated to contiguous areas of memory in internal
(2) Dynamic memory area allocation
ROM D=R
START P,C,D/400,R,B/20000
(a) Contents of dynamic memory
The following two types of dynamic memory areas are used in C/C++ programs:
Stack area
Heap area (for memory allocation of library functions and other uses)
P, C, D, B: Default section names generated by the compiler.
R: Section name specified by ROM support function of the linkage editor.
0x000000
0x000400
0x020000
0xFFEC00
0xFFFBFF
load module. When symbols allocated to section D are referenced, relocation is
performed so that their addresses are in section R. Section D and section R are
initialized data sections on ROM and to RAM respectively.
ROM starting from address 0x400. Sections R and B are allocated to contiguous
memory areas starting from address 0x20000 in RAM.
