Interface MipsMemory

All Superinterfaces:

Memory

All Known Implementing Classes:

Cache, HadesInterface, MemoryDispatcher, NullMemory, TinyBPMemory, TinyMemory

public interface MipsMemory

extends Memory

Low level interface for memory access, implemented by the different caches and the interface to HADES. Only word accesses on word aligned addresses are allowed.

Method Summary

boolean	beginCycle() next cycle, perform access to lower layer if needed, wait returned
void	endCycle() end of a cycle, all core actions are done, memory actions can complete
boolean	finished() request end of read or write access
boolean	getHit(int adr) Is data present at the specified address?
java.lang.String	getName() get the name of this memory
int	getReadResult() get the result of the last read operation
void	read(int adr, boolean burst) Drive busses for read access
void	setName(java.lang.String newName) Set the name of this memory
void	write(int adr, int data) Drive busses for write access
