Is multiprocessor debugging multithreaded debugging?

[Anupama Chandwani]

Hello, i would like gdb to remote debug a homogeneous multiprocessor
chip (with no OS) from my linux box. I want to use only a single
session of gdb. How different is it from debugging multi-threaded
programs? i.e Can each processor be treated as a thread? However there
are different code images on each processor..
