3.1.6. Southbridge

The Southbridge is an FPGA (Xilinx XC4VLX40) and provides the majority of the system peripherals. It also implements the system control and configuration functions required by the PB-A8. See Southbridge for details.


The majority of the controllers and interfaces implemented in the Northbridge and Southbridge are ARM PrimeCell® components.


The image loaded into the Southbridge FPGA must match the system configuration or both the baseboard and an attached Logic Tile may be damaged. A copy of the configuration FPGA image is supplied on the Versatile Family CD in case of accidental corruption of the preloaded image. See Appendix G Loading FPGA Images for details.
