The Implementation of TLM Simple Bus in SystemC¹

In this project, there are the following c++ files:

• simple_bus_main.cpp:
• simple_bus_test.h: the testbench, descriptions the instance of the modules and the inter connections.
• simple_bus_master_blocking.h: the blocking master's ports, the constructor as well as private values.
• simple_bus_master_blocking.cpp: the blocking master's process function.
• simple_bus_master_non_blocking.h:
• simple_bus_master_non_blocking.cpp: the process function.
• simple_bus_master_direct.h:
• simple_bus_master_direct.cpp: the process function.
• simple_bus_slow_mem.h: including the implementations of the slave interface.
• simple_bus_types.h:
• simple_bus_blocking_if.h: the blocking interface
• simple_bus_direct_if.h: the direct interface
• simple_bus_non_blocking_if.h: the non blocking interface
• simple_bus_request.h:
• simple_bus_slave_if.h: the slave interface
• simple_bus.h:
• simple_bus.cpp: including the implementations of master interfaces.
• simple_bus_fast_mem.h: including the implementations of the slave interface.
• simple_bus_arbiter.h:
• simple_bus_arbiter_if.h: the arbiter interface
• simple_bus_arbiter.cpp:
• simple_bus_types.cpp:
• simple_bus_tools.cpp:

Implementation of Masters

Implementation of Bus

Dynamic Sensitive

  wait(request->transfer_done); // event, dynamic
  wait(clock->posedge_event()); // statically sensitive (activated every cycle)

Implementation of Slaves
