Randy Suen Posted December 14, 2022 Report Share Posted December 14, 2022 Hi everyone, As we know the master (initiator) and slave (target) interfaces of a bus usually support "outstanding". In my bus model, I use buffers (std::vector<*tlm_generic_payload>) to store outstanding requests. But I'm not sure this is a good choice. Is it possible to describe "outstanding" just using TLM without such explict buffers? Quote Link to comment Share on other sites More sharing options...
David Black Posted January 2 Report Share Posted January 2 If you are using TLM-2, you should be only buffering the references and not the data itself. Backpressure can be modeled using the TLM_ACCEPT mechanism. If your bus allows more than one outstanding request, you will need some form of storage for those references, and std::vector should be fine.
