Spontaneous Information Systems

Contact : Frédéric Weis

Pervasive Computing Activity

key words : Spatial navigation, physical programming, wireless communications

Spatial PRogramming Environment Ambient computing Design (Spread)

Contact : Paul Couderc

Scractchy Activity

key words : Java runtimes, embedded systems, wireless appliances, soft real-time scheduling

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.
