Functional Description
ATCA-8310 Installation and Use (6806800M72E) 97
The programmable logic required on ATCA-8310 (Windsor) resides in a Glue Logic FPGA. It
implements special functions, like:
 LPC Bus Interface connected to GPP
 LPC Host Interface connected to IPMC. Local Bus to LPC Bridge. Includes SERIRQ. Emulates
KCS Interface
 Local Bus connected to SPP to access Glue Logic FPGA Register
 IPMC SPI interface connected through CPLD to access Glue Logic FPGA Register.
 GPP/SPP Shared Memory
 SPI Interface to update Glue FPGA Configuration Flash
 Two Serial Interfaces COM1 and COM2 usable via Super IO mapping for GPP
 Watchdog Controller for GPP and SPP
 Reset Controller for GPP and SPP
 Routing of internal and externals GPP Interrupts via SERIRQ protocol
 Routing of internal and externals SPP Interrupts to SPP interrupt input signals
 Interrupt masking of GPP and SPP interrupts
 GPP Post Code Register (For Debugging support)
 Telecom Clock Support
 DMC Module support
 GPP and SPP Boot SPI flash selection support
 Miscellaneous Registers (e. g. Version Register, User LED control)
