      intGen.c

DESCRIPTION -
	      This demo generates a VMEbus interrupt to demonstrate
	      synchronization among tasks on multiple CPUs.

	      The intGen() routine counts down from the initialized countdown 
	      value to zero and then generates VME bus interrupt to synchronize
	      with a task running on CPU 1.  This program is meant to be
	      run on CPU 0.

	      The intGen task runs on CPU 0, intSync task runs on CPU 1

	      To run this demo invoke the function 
	      intGenDemo(intSyncTargetArchType) where intSyncTargetArchType is 
	      the value for the intSync task's target architecture type.
	      Possible intSyncTargetArchType values and corresponding
	      architecture types are given below:
	      value     architecture type

RUNNING DEMO -
	       You need to set/change the value of INTNUM constant
	       (VMEbus interrupt number to which intSync task's ISR
	       is connected) and intNum variable (interrupt number
	       for generating VMEbus interrupt).

	       Some VMEbus Single Board Computer systems can not generate
	       VMEbus interrupts. Check your hardware and board specific
	       BSP documents for VMEbus interrupts support.

	       Place the intGen.c file in your <Tornado> dir.
	       Depending on the target you have, define the CPU in your compile 
	       line and use the Makefile in the BSP dir. to compile.
