Means for Servicing a Hardware Simulation Accelerator

      Disclosed is a method of efficiently providing service by a
software processor to a hardware simulation accelerator.

      During execution of a simulation cycle, requests and events may
be signalled by a hardware simulation engine which require service
from a processor.  In some cases, the signalling device has to wait
for a response before continuing, so efficient handling of the
requests is important.  Once the host processor software has started
a simulation cycle in the hardware engine, control is passed to an
event polling loop.  This routine continually polls the hardware
engine for a ready indication.  This ensures that the processor will
respond to a request or event as quickly as possible.
