Chapter 2: ML310 Embedded Development Platform

Non-Volatile Storage

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.

XC2VP30 Connectivity

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. Table 2-4shows the connection between the System ACE and the XC2VP30. It shows the signal names with associated pins on System ACE and the XC2VP30 for both the MPU interface.
