//~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
// DESCRIPTION
//   This is an example of a simple processor using clocked threads
//   (SC_CTHREAD) and watching constructs. This example uses elements
//   from other examples such as an event only clock (ea_heartbeat), a
//   pullup resolved channel (ea_pullup), a custom port (ea_heartport),
//   and a custom primitive channel (mem_arch). This example represents
//   a custom processor as might be used to manage operations on a
//   collision avoidance radar unit. No emphasis on performance has been
//   made.
