Description copied from class: SystemMemory

This method is called to build and configure the memory system for the newly allocated processor array. In particular, shared memories should be allocated and connected to processors here. This method may also be used to adding additional banks of local memories or manipulating the default local memory, although this could also be done locally.

Specified by:

configureMemory in class SystemMemory

Parameters:

mp - The multiprocessor.

Throws:

SystemMemoryException - if there is a problem allocating or using the memory objects.
