US 7039831 B2 During debugging of target system by a host
system, s single stack is used for an exception by a set of
applications running on the processor of the target. To achieve
this, the stack is dynamically loaded by the host to a reserved
memory region, and a vector of the target is set to point to
that reserved memory region. The exception handlers of each
application then use the vector to access the stack. 1. A method
of debugging a target system using a host system connected
thereto, the target system comprising a digital signal processor
having associated memory comprising plural addressable
locations, said target system further having a reserved storage
location designated as a vector address, said memory further
storing a plurality of application programs, each application
program having respective associated exception handler code, the
method comprising: dynamically loading a stack to a reserved
region of said memory; causing the vector address of said target
system to point to said stack, wher
