At the same time we have witnessed that performance does not always keep pace with expectations in many services like multimedia services and biomedical applications. Moreover, the IT market has suffered from some crashes. Hence, this triggered us to think of making use of available technologies and developing new ones so that the performance level is suitable for given applications and services. In the medical field, from a statistical viewpoint, the biggest diseases in number of deaths are heart diseases, namely Cardiovascular Disease (CVD) and Stroke.

The current development system for 6.115 is the 386 EX evaluation board. The current development system has been extended by having the 68HC 11 microcontroller control peripheral devices. The original intention was to develop such a system around the PowerPC line of processors, however the availability of the 386EX evaluation board, and its adoption into 6.115 led to its being the choice for the extension. The results of this initial development work are the creation of a microprocessor based system that is capable of processing data directly from an analog to digital converter under 68HC1 l's control.
