2.3.1. HPS Block Diagram

The figure below is a detailed block diagram of the HPS and dual I/O bank MPFE. It consists of the following blocks:
  • MPU—contains the Arm* Cortex* processor and DSU
  • APS—contains the CCU, I/O coherent fabric bridge, GIC, SMMU, and OCRAM
  • PSS—contains the PSI interface to the SDM, the HPS-to-FPGA/FPGA-to-HPS bridges, the PSS NoC, and all the peripherals.
  • MPFE—provides an interface to the SDRAM from both the fabric and the HPS.
