In addition to programming the FPGA and storing bitstreams, System ACE can be used for
general use non-volatile storage. System ACE provides an MPU interface for allowing a
microprocessor to access the CompactFlash, allowing the use of the CompactFlash as a file
system.
System ACE is connected to the XC2VP30 through both the JTAG chain, for configuration,
and through the MPU port of the System ACE, for allowing the XC2VP30 to control System
ACE and access the CompactFlash.
ACE and the XC2VP30. It shows the signal names with associated pins on System ACE and
the XC2VP30 for both the MPU interface.
