Interfaces, channels and ports

Introduction
• In classical hardware modeling, the hardware signal is the medium
for communication and synchronization between processes
– Signals are at a very low level of abstraction
• Interfaces, ports and channels are the way through which SystemC
implements synchronization and communication at system level
– Interfaces: they define a set of methods, but do not implement
these methods
– Channels: they implement one or more interfaces
– Ports: they enable a module, and hence its processes, accessing a
channel's interface
