Data Flow diagram in Sloss book, ARM Development

Hi to all on the ARM forum,
I'm new to ARM and have some questions:
The DATA FLOW diagram in the Sloss book, Arm Development, has several connections/buses which do not exist in the ARM documentation ( as far as I can see ).
They are :(1) connection direct from the MAC to the ALU bus
(2) a bus from the Register File direct to the MAC labeled Acc ( Accumulator bus )
ARM documents indicate that the MAC connects ONLY between the A and B buses
Can someone explain where I am misinterpreting , or missing the point somewhere ?
Any help will be very much appreciated, thanks
Skippy
