Floating-Point Digital Signal Processors
SPRS370C–SEPTEMBER 2006–REVISED OCTOBER 2007
A high-level memory map of the C672x DSP appears in
Table 2-8
. The base address of each region is
listed.
Any address past the end address must not be read or written.
The table also lists whether the
regions are word-addressable or byte- and word-addressable.
