System ACE™ MPM Solution
R
Identical configuration of multiple target FPGAs from a sin-
gle bitstream can be achieved through the appropriate con-
nections. See Figure 9 for an example of two FPGAs that
are simultaneously configured from a single bitstream.
The System ACE software assigns bitstreams for the target
FPGAs in order, starting from the CFG_CS[0] pin through
CFG_CS[N-1] pin where N is the number of Slave-Select-
MAP devices in the system. N may be up to four devices.

Configuration Data
The configuration data sets for the target FPGAs are stored
in a standard, high-density Flash memory unit in the System
ACE MPM.
Data Storage
The System ACE MPM integrates a standard Flash memory
unit for storage of the configuration data sets. See Table 12.
The System ACE MPM product family offers data storage
capacity up to 64 Mb. See the Flash memory vendor’s data
sheets for additional information about the Flash memory
unit in the System ACE MPM. See Table 13 for Flash mem-
ory data sheet references.
