Progress in hardware technology enables to envision the use of
wireless appliances for the execution of applications traditionally
supported on the desktop. In that context, the user will be provided
with an open environment that allows him to perform actions as
diverse as Internet accesses, application downloading, and phone
calls. However, the actual provision of the aforementioned environment
on the wireless appliance is far from being straightforward; hardware
and software solutions still need to be devised. About the hardware,
Texas Instruments is going to propose a new hardware solution
based on heterogeneous multiprocessor integration. About the software,
a wireless software environment must meet the following requirements:
(1) Maximize efficiency so as to support efficient
execution of applications, possibly run concurrently.
(2) Minimize power consumption so as to provide users with highly
autonomous, small-sized appliances.
(3) Maximize availability so that users can benefit from their
appliances despite the occurrence of failures.
(4) Support multimedia applications, which have soft real-time
constraints.
(5) Support dynamic downloading of applications (e.g. through
Internet)
A Java environment appears to be an ideal candidate
to achieve requirement (5). Furthermore, the de facto standard status
of Java leads to have a significant amount of available software,
which will continue to grow. However, providing a Java environment
for Texas Instruments appliances that both supports multimedia applications
and exploits the underlying hardware potential (i.e. an environment
that meets the above five requirements) is an open issue and constitutes
the core of the collaboration with Texas Instruments.
