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 demonstration of how error handling during
implicit loading is possible. The error handler here signals an exception
(implemented by a call to longjmp, to let the error be handled at a higher
level in the application. 

When the error handler does not exit, or signal an exception (that is,
when it just returns to its caller), the dynamic loader will retry the
load. So in this case, the error handler should try to remove the error
condition. This is most useful in case of a load failure due to memory
overflow: by cleaning up memory and returning, the system can proceed
after error handling without the application even noticing a problem.
