# Class: com.pnfsoftware.jeb.core.units.code.asm.processor.arch.AbstractRegisterBank

Base implementation of a registers bank layout. 

 It is preferable to use [AbstractRegisterBank2](AbstractRegisterBank2) to define register banks.

## Constructor: AbstractRegisterBank


## Static Field: REG_GRP_GP
Type: `int`

Constant value: `0`
Description: Group for general\-purpose registers: always 0.

## Static Field: REG_GRP_SPECIAL
Type: `int`

Constant value: `1`
Description: Group for non\-GP registers and registers not fitting in other user\-created groups.

## Method: format
