用于TM1300/PNX1300系列DSP（主要用于视频处理）的动态下载程序源码。

This demo contains a simple application dispatcher, for running
applications that have been linked using tmcc/tmld option -btype app,
as in 

[59] tmcc -btype boot hello.c -o a.out
[60] tmcc -btype app  hello.c -o a.app

As the following tmsize output shows, such an a.app is considerably smaller
than a regular a.out, because the runtime system is not included in the
.app. Instead, this runtime system should be part of the dynboot executable
that loads the .app.
Also, exactly because all host specific (IO-) libraries are part of
the dynboot executable, the .app can be kept host independent.
This implies that, given the proper dynboot executable, the .app
 can be executed on any host (MacOS, tmsim, Win95).

[61] tmsize a.out
text    data    data1   bss     dec        hex        
65408   868     648     2708    69632      0x11000   
 
[62] tmsize a.app
text    data    data1   bss     __mdesc__ $String$DynLoad$ $Ext_Mod$DynLoad$ dec        hex        
384     0       21      0       100       10               24                539        0x21B      


appshell.out is such a dynboot executable. It takes as arguments
the name of an application file, plus the arguments that should be passed to it.
An appshell should be made for each different host/each endianness,
and by these, an app should be runnable on any platform.

examples:
