Method Detail

configureMemory

public abstract void configureMemory(Multiprocessor mp)
                              throws SystemMemoryException

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.

Parameters:

mp - The multiprocessor.

Throws:

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

get

public static SystemMemory get(java.lang.String systemMemoryClassName)
                        throws SystemMemoryException

This method is used to return a newly allocated System Memory definition class.

Parameters:

systemMemoryClassName - The name of the class in the cmp.cmpware.cmp.models package used to define the global memory system for this multiprocessor.

Throws:

SystemMemoryException - if there is any problem allocating or accessing the System Memory class.
