Method Details

getBank

public static IRegisterBank getBank(ProcessorType proctype)

Convenience method to retrieve a register bank used by a well-known processor type.

It is recommended to use RegisterBankService directly.

Parameters:

proctype - a processor type

Returns:

null if not found

createRegisterId

public static long createRegisterId(int index,
 int grp,
 int bitsize)

Create a standard register id (full or slice).

Parameters:

index -

grp -

bitsize -

Returns:

createRegisterId

public static long createRegisterId(int index,
 int grp,
 int bitsize,
 int bitstart)

Create a standard register id (full or slice).

Parameters:

index -

grp -

bitsize -

bitstart -

Returns:

createPureRegisterId

public static long createPureRegisterId(int index,
 int grp)

Create a pure register id, i.e. an id always representing a full register, without indicators such as bit size or bit start.

Parameters:

index -

grp -

Returns:

createRegisterIdFromPureId

public static long createRegisterIdFromPureId(long pure,
 int bitsize,
 int bitstart)

isPureId

public static boolean isPureId(long id)

getPureId
