spawned and unspawned process

[karandeep963]

Hello All,

 

I just cant understand spawned and unspawned processes. Can anyone please relate it with some good examples.

Hi KS,

 

If you are just starting out with SystemC, you can probably safely ignore dynamic (spawned) processes - just use SC_METHOD or SC_THREAD in the module's constructor. Dynamic processes can be useful for advanced cases (e.g. responding to some condition that is not known at compile time).

Hello dave,

 

Are the dynamic and static processes or the spawned and unspawned processes same concepts?????

Hi Amit,

Pretty much - static processes are created using the SC_METHOD and SC_THREAD macros. Dynamic processes are created by calling sc_spawn. There is one slight complication, calling sc_spawn from a module's constructor will actually create a static process since the LRM defines a dynamic process as one created from "the end_of_elaboration callback or during simulation" (see Glossary B.51). The LRM uses the term "spawned" and "unspawned" to try to avoid this confusion!

"calling sc_spawn from a module's constructor will actually create a static process"

What is the meaning of Quoted line.

It means

 

"calling sc_spawn from a module's constructor will actually create a static process"

 

- I don't know what you don't understand. Can you ask a more specific question?

Hello alan,

 

Are u saying like follwing???

 

SC_CTOR()

{

sc_spawn(process_a) 

}

 

if process_a is registered as sc_spawn in constructor.

So now process_a become static???
