DSM2150F5V
ARCHITECTURAL OVERVIEW
Major functional blocks are shown in Figure 4.
DSP Address/Data/Control Interface
These DSP signals attach directly to the DSM for
a glueless connection. An 8-bit or 16-bit data con-
nection is formed and 16 or more DSP address
lines can be decoded as well as various DSP
memory strobes; i.e.
etc. The data path width must be specified as 8-
bits or 16-bits in PSDsoft Express. This configura-

tion is a static, meaning the data path width cannot
switch between 8-bits and 16-bits during runtime.
Port F is used for 8-bit data path, Ports F and G are
used for 16-bit data path. There are many different
ways the DSM2150F5V can be configured and
used depending on system requirements. See Ap-
pendices for example connections between the
DSM2150F5V and different DSPs.
