TYPICAL MEMORY MAP
There many different ways to place (or map) the
addresses of DSM memory and I/O depending on
system requirements. The DPLD allows complete
mapping flexibility. Figure 7 shows one possible
system memory map. In this case, the DSP will
bootload (via DMA) the contents of Main Flash
memory upon reset. The Secondary Flash memo-
ry can be used for parameter storage or additional
code storage.
BMS
and
MSx
are configured in the
DSP to be combined into the
BMS
signal, allowing
the DSP to access both Flash memories at runt-
ime (after DMA boot). The DSP may execute code
directly from the DSM and well as erase and write
new code or data to DSM Flash.
The nomenclature fs0..fs7 are designators for the
individual sectors of Main Flash memory, 32K
bytes each. csboot0..csboot3are designators for
the individual Secondary Flash memory seg-
ments, 8K bytes each. csiop designates the DSM
control register block.
The designer may easily specify memory mapping
in a point-and-click software environment using
