用于TM1300/PNX1300系列DSP（主要用于视频处理）的下载程序

This example shows a simple program that uses the downloader library 
for generating a load image from an executable. Memory images can be
generated at compile/link time using the -mi option of tmld, but it is
not always convenient to do so. For instance, it might not be known
at compile/link time on which board the produced executable is to 
be executed, or maybe the executable is to be executed on multiple
boards, each with their own SDRAM size / offset, processor frequency, etc.

Loaders like tmrun, tmgmon etc that allow load/execute of arbitrary 
executables use the downloader library as in the example program
for generating an absolute load image from a relocateble executable
in the TriMedia object format, while also filling in some critical
values like processor frequency. Also tmld itself uses the downloader
library in this way, for implementing the -mi option.

This examplegenerates a sample memory image file using tmld (see Makefile),
and it generates another one in an equivalent way using the downloader
library (see C program). The resulting memory images should hence be
identical, and this is checked in the makefile.

NOTES:

    - all error checking is omitted in the C program

    - all parameters (file names SDRAM details etc) 
           are hardcoded in the C program

    - For a complete description of the downloader library,
           see the TriMedia reference manuals

    - The makefile demonstrates how to build the 
           downloader program as a Sun executable
           and as a TM executable, using both forms
           of the libraries available in the SDE.
           Only the TM1 version is used.
