Threads and Methods

SystemC enables a user module to keep a thread and a stack but prefers, for efficiency reasons if user code runs on its own upcalls in a trampoline style.

• An SC_THREAD has a stack and is allowed to block.
• An SC_METHOD is just an upcall from the event kernel and must not block.

Comparing SC_THREADs with trampoline-style methods we can see the basis for two main programming TLM styles to be introduced later: blocking and non-blocking.
