The DSPs exchange data with their environments (on-chip or off-chip)
through several buses. Refer to your DSP's data sheet and Hardware Refer-
ence manual.
The linker places data in memory according to the constraints imposed by
your system's architecture. For this purpose, the
command specifies the placement order of bytes in memory. This ordering
places data in the same sequence required by the DSP as it transfers data.
