Abstract:
One of the fastest expanding areas of computer exploitation
is in embedded systems, whose prime function is not that of
computing, but which nevertheless require information
processing in order to carry out their prime function.
Advances in hardware technology have made multi
microprocessor systems a viable alternative to uniprocessor
systems in many embedded application areas.
This thesis reports the results of investigations carried out
on multi microprocessors oriented towards embedded
applications, with a view to enhancing throughput and
reliability.
An ideal controller for multiprocessor operation is developed
which would smoothen sharing of routines and enable more
powerful and efficient code I data interchange. Results of
performance evaluation are appended.A typical application scenario is presented, which calls for
classifying tasks based on characteristic features that were
identified. The different classes are introduced along with
a partitioned storage scheme. Theoretical analysis is also
given.
A review of schemes available for reducing disc access time
is carried out and a new scheme presented. This is found to
speed up data base transactions in embedded systems.
The significance of software maintenance and adaptation in
such applications is highlighted. A novel scheme of
prov1d1ng a maintenance folio to system firmware is
presented, alongwith experimental results.
Processing reliability can be enhanced if facility exists to
check if a particular instruction in a stream is appropriate.
Likelihood of occurrence of a particular instruction would be
more prudent if number of instructions in the set is less. A
new organisation is derived to form the basement for further
work. Some early results that would help steer the course of
the work are presented.
