      Parameters:
      registerName - register name
      groupName - group name
      Returns:
      true if register was found, else false

    • setFlag

      public boolean setFlag(String registerName, int registerFlag)
      Set a register flag for the specified register
      Parameters:
      registerName - register name
      registerFlag - Register defined flag bit(s)
      Returns:

    • addLaneSize

      public boolean addLaneSize(String registerName, int laneSizeInBytes)
      Add a vector lane size to the specified register.
      Parameters:
      registerName - register name
      laneSizeInBytes - the size of the lane to add in bytes
      Returns:
      true if register was found, else false
      Throws:
      UnsupportedOperationException - if register is unable to support the definition of lanes.
