Re: [Gems-users] cache coherence

[Greg Byrd <gbyrd@xxxxxxxx>]

You're not allowed to provide parameters for an action.

The "address" is implicitly bound to the address of the line that is being acted on.  (The line that caused whatever transition is invoking this action.)

There are other implicitly-declared variables:  in_msg is bound by the "peek" statement, and out_msg is bound by the "enqueue" statement.

Hi,all

sorry,the last message has some errors,I update it now.

In the file MESI_CMP_filter_directory-L2cache.sm,there are lots of actions,and almost each action has a parameter "address",for example as follows,

// ACTIONS

  action(a_issueFetchToMemory, "a", desc="fetch data from memory") {

    peek(L1RequestIntraChipL2Network_in, RequestMsg) {

      enqueue(DirRequestIntraChipL2Network_out, RequestMsg, latency="L2_REQUEST_LATENCY") {

        out_msg.Address := address;

        out_msg.PhysicalAddress := in_msg.PhysicalAddress;

        out_! msg.Type := CoherenceRequestType:GETS;

        out_msg.Requestor := machineID;

        out_msg.Destination.add(map_Address_to_Directory(address));

        out_msg.MessageSize := MessageSizeType:Co! ntrol;

      }

    }

  }

I donnot know where the parameter "address" defined.when I add a new parameter,it warns to me "error:unrecognized variable".I grep "address" but no results.Could anyone  help me? Thanks in advance!
