From 2a740aa09682c32eb8f1f8880f279c943d8c6ee1 Mon Sep 17 00:00:00 2001 From: Andreas Hansson Date: Mon, 15 Oct 2012 08:12:35 -0400 Subject: Port: Add protocol-agnostic ports in the port hierarchy This patch adds an additional level of ports in the inheritance hierarchy, separating out the protocol-specific and protocl-agnostic parts. All the functionality related to the binding of ports is now confined to use BaseMaster/BaseSlavePorts, and all the protocol-specific parts stay in the Master/SlavePort. In the future it will be possible to add other protocol-specific implementations. The functions used in the binding of ports, i.e. getMaster/SlavePort now use the base classes, and the index parameter is updated to use the PortID typedef with the symbolic InvalidPortID as the default. --- src/mem/mem_object.hh | 16 ++++++++++------ 1 file changed, 10 insertions(+), 6 deletions(-) (limited to 'src/mem/mem_object.hh') diff --git a/src/mem/mem_object.hh b/src/mem/mem_object.hh index 6cc0c4fd3..e12b30661 100644 --- a/src/mem/mem_object.hh +++ b/src/mem/mem_object.hh @@ -67,26 +67,30 @@ class MemObject : public ClockedObject MemObject(const Params *params); /** - * Get a master port with a given name and index. + * Get a master port with a given name and index.
