3. System requirements

This software will run on any PC/ mac etc that has the requirements below:

Pentium P90 processor

32 MB RAM

5 MB free HDD space*

Java Runtime Environment 1.3 installed

*The free HDD space figure does not include space needed for virtual memory.

PCNGui can use a considerble amount of memory when dealing with large networks. The size of the network is dependant on the number of layers in each group. A network consisting of three layers in each group may use about 50 MB, where as eight layers in each group may use up 100 MB. As the software supports the option to open and simulate multiple networks the memory usage can increase dramatically when more than one is opened. Most operating systems allow the HDD to be used as virtual memory but there must be enough free space.

A fast processor is preferable as the recognition process can take some time to complete. For example on a 466Mhz processor the recognition time for a simple network with three layers in each group is about seven seconds. This is adequate when many hundreds of unknown patterns may need to be classified.

The Java runtime environment can obtained free from the site below:
