The DSP isn't implemented as a simple co-processor, OMAP contains more
than one physical processor in the package. (Including the ARM MPU and
the c55x DSP). MPU in this case refers to Micro-Processing Unit, which
refers to the primary ARM in the OMAP. Anyone even vaguely familiar with
TI and OMAP literature should be aware of this, hopefully this should
clear things up. Calling it ALU-based decoding would be misleading, as
vendors have a tendency to implement barrel shifters in hardware outside
of the scope of the ALU. ;-)
