21160 ldf file

Started by Matthew Rensing November 15, 2000
I've noticed that the default ldf file for the 21160 processor in VisualDSP
(SP 4.1.3) includes a rather sizeable 16k memory hole between the end of
dmda and the start of the heap. There are similar holes found in the
default ldf files for the 21060 and the 21062, but not the 21061 or the
21065L. I've not been able to come up with a good reason for this, or as to
why I should leave this memory unused. Any insight that anyone can offer on
this would be greatly appreciated. I do understand the need for the hole
between pmco and pmda (due to the transition from 48-bit wide memory to
32-bit wide memory), but that is obviously not the case here.

Thanks,
Matthew Rensing
