The WDP contains a set of processes, which is divided
into standard processes:
- PU drivers
- VDU driver
- LP driver
- CCB driver
- KERNEL
and application processes:
- PU handler
- SYS M&C
- VDU handler
- LP handler.
The interactive communication between the processes
is done via semaphore queues. The processes, which
are not waiting in a semaphore queue, are given CPU
time by the KERNEL, cf CDS-MIC/003/USM/0003.
Fig. 4.2.8.1-1 gives the allocation of the functions
onto the processes.
Fig. 4.2.8.2-1 gives a software structure overview.
