ABSTRACT:
The combination of Ada's new classwide programming with tagged types,
generics (templates), and representation clauses for both enumerated and
record types greatly facilitates low level programing. A generic board
register class was extended to represent the specific hardware and provide
high level abstractions for reading and changing the states of the hardware
registers.  Objects derived from this generic board register class include
functions and procedures which address these registers by name and employ
high-level syntax for bit manipulation.  The use of these objects permits
the development of easily understood, maintainable software for computer
boards which control and acquire data from devices including scientific and
medical instruments. A software library providing these and other relevant
functionalities and an application with a commercial 100 megahertz scaler
board for a PCs will be described.

Keywords:
Object Oriented Programming, OOP, Device, Board, Low-level, Ada, Ada 95,
Embedded system.
