HPS-to-FPGA bridge is mastered by the L3 slave peripheral switch.
The FPGA-to-HPS bridge masters the L3 main switch, allowing any master implemented in the
FPGA fabric to access most slaves in the HPS. For example, the FPGA-to-HPS bridge can access
the accelerator coherency.
All three bridges contain global programmer view GPV register. The GPV register control the
behavior of the bridge. It is able to access to the GPV registers of all three bridges through the
lightweight HPS-to-FPGA bridge.
This Demo introduces to users how to use the HPS/ARM to communicate with FPGA. This project
includes GHRD project for the HAN Pilot Platform one ARM C Project which demonstrates how
HPS/ARM program controls the LEDs connected to FPGA.

The term GHRD is short for Golden Hardware Reference Design. The GRD project provide by
Terasic for the HAN Pilot Platform is located in the CD folder: CD-ROM\ Demonstration\
SOC_FPGA\ a10s_ghrd.
The project consists of the following components:
ARM Cortex™-A9 MP Core HPS
Two user push-button inputs
Two user DIP switch inputs
Two user I/O for LED outputs
256 KB of on-chip memory
JTAG to Avalon master bridges
Interrupt capturer for use with System Console
System ID
The memory map of system peripherals in the FPGA portion of the SoC as viewed by the MPU
starts at the lightweight HPS-to-FPGA base address 0xFF20_0000. The MPU can access these
peripherals through the Address offset setting in the Qsys. User can open the GHRD project with
Quartus Software. Then open the a10s_ghrd.qsys file with the Qsys tool.
