6 Instrumentation Programming
6-1 TASK SUN/134.2
Guide to Writing ADAM Instrumentation Tasks
An introductory guide to writing ADAM “real-time” instrumentation tasks.
This document includes a description of the ADAM tasking model and
develops real-time concepts through a series of examples. It also describes the
library of ADAM TASK routines.
6-2 NBS SUN/77.2
NBS provides a mechanism for the rapid transfer of large quantities of data
between processes running on the same processor. It utilises shared memory
in which a hierarchical data structure (a “noticeboard”) may be built and
subsequently written and read by co-operating processes. Noticeboards are
typically used in data-acquisition environments, but this does not preclude
their use for other purposes. The data-structuring facilities of NBS are broadly
similar to those of HDS (see SUN/92), although noticeboards have a static
structure and are volatile.
6-3 MSP SSN/2.1
Message System Primitive Routines
These routines provide the low-level message-passing services upon which
inter-task communication within ADAM depends. They will normally only be
of use to ADAM system programmers or those developing real-time ADAM
