Attach memory of size, at location

isMapped

public boolean isMapped(int address)

Answer if this address is mapped.

doCycle

public void doCycle()

Give each block a cycle

Specified by:

doCycle in interface Memory

initialize

public void initialize()

Initialize each block

Specified by:

initialize in interface Memory

getSize

public int getSize()

Specified by:

getSize in interface Memory

readWord

public int readWord(int address)

Read a word at the given address. If there is no memory mapped at that address, an exception in the simulator is raised.

Specified by:

readWord in interface Memory

readByte

public byte readByte(int address)

Read a byte at the given address. If there is no memory mapped at that address, an exception in the simulator is raised.

Specified by:

readByte in interface Memory

writeWord

public void writeWord(int address,
                      int value)

Write a word at the given address. If there is no memory mapped at that address, an exception in the simulator is raised.

Specified by:

writeWord in interface Memory

writeByte

public void writeByte(int address,
                      byte value)

Write a byte at the given address. If there is no memory mapped at that address, an exception in the simulator is raised.

Specified by:
