SPECIFYING THE MEMORY MAP WITH PSDSOFT EXPRESS
TM
The memory map shown in Figure 7 can be easily
implemented using PSDsoft Express
TM
in a point-
and-click environment. PSDsoft Express
TM
will
generate Hardware Definition Language (HDL)
statements of the ABEL language. Figure 8 shows
the resulting equations generated by PSDsoft Ex-
press
TM
.
Figure 8. HDL Statements Generated from PSDsoft Express to Implement Memory Map
Specifying these equations using PSDsoft Ex-
press
TM
is very simple. Figure 9 shows how to
specify the equation for the 32K Byte Flash mem-
ory segment, fs2 Notice fs2is qualified with the
signals
BMS
. This specification process is repeat-
ed for all other Flash memory segments, the csiop
register block, and any external chip select signals
that may be needed (ADC, etc.).
