1MB L1P/L1D 1M bytes boundaries on DM6437?

Hi,

I would like to ask a question on L1 memory.

In page 24 and 50 of spru871k, TMS320C64x+ Megamodule Reference Guide (Rev. K), both L1P and L1D are described to be constrained on 1MB boundaries.

However, on page 14 of sprs345d, TMS320DM6437 Digital Media Processor:

Clearly, none of the three is 1MB boundary. So how should I understand spru871k’s description in view of the real L1P/L1D layout of DM6437?
