Method Detail

setSize

public static void setSize(RawProcElements chip)

getStrDram

public static StreamingDram getStrDram(Address addr,
                                       RawProcElements chip)

getUB

public Address getUB()

getLB

public Address getLB()

setTiles

public static void setTiles(RawChip chip)

Set the tile(s) that is(are) mapped by the hardware to this dram. Note that we use a different mapping in our compiler so we must communicate some address between allocating tiles and logical owner tiles.

Parameters:

chip -

setBounds

public static void setBounds(RawProcElements chip)

printDramSetup

public void printDramSetup()

printSetup

public static void printSetup(RawProcElements chip)

toString

public String toString()

Overrides:

toString in class Object

resetFileAssignments

public void resetFileAssignments()

setFileReader

public void setFileReader(FileInputContent file)

setFileWriter

public void setFileWriter(FileOutputContent file)
