Chapter 1: Overview for the Arria V Device Family
SoC FPGA with HPS
System Peripherals
The Ethernet MAC, USB OTG controller, NAND flash controller and SD/MMC/SDIO
controller modules have an integrated DMA controller. For modules without an
integrated DMA controller, an additional DMA controller module provides up to
eight channels for high-bandwidth data transfers. The debug access port provides
interfaces to industry standard JTAG debug probes and supports ARM CoreSight
debug and core traces to facilitate software development.
HPS-FPGA AXI Bridges
The HPS–FPGA bridges, which support the Advanced Microcontroller Bus
Architecture (AMBA
®
) Advanced eXtensible Interface (AXI
) specifications, consist
of the following bridges:
FPGA-to-HPS AXI bridge—a high-performance bus supporting 32-, 64-, and
128-bit data widths that allows the FPGA fabric to master transactions to the slaves
in the HPS
HPS-to-FPGA AXI bridge—a high-performance bus supporting 32-, 64-, and
128-bit data widths that allows the HPS to master transactions to the slaves in the
FPGA fabric.
Lightweight HPS-to-FPGA AXI bridge—a lower performance 32-bit width bus
that allows the HPS to master transactions to the slaves in the FPGA fabric.
The HPS–FPGA AXI bridges also allow the FPGA fabric to access the memory shared
by one or both microprocessors, and provide asynchronous clock crossing with the
clock from the FPGA fabric.
HPS SDRAM Controller Subsystem
The HPS SDRAM controller subsystem contains a multiport SDRAM controller and
DDR PHY that is shared between the FPGA fabric (through the
FPGA-to-HPS SDRAM interface), the level 2 (L2) cache, and the level 3 (L3) system
interconnect. The FPGA-to-HPS SDRAM interface supports AMBA AXI and Avalon
®
Memory-Mapped (Avalon-MM) interface standards, and provides up to four ports
with separate read and write directions.
To maximize memory performance, the HPS SDRAM controller subsystem supports
command and data reordering, deficit round-robin arbitration with aging, and
high-priority bypass features. The HPS SDRAM controller subsystem supports DDR2,
DDR3, LPDDR, or LPDDR2 devices up to 4 Gb and runs up to 533 MHz (1066 Mbps
data rate).
For easy migration, the FPGA-to-HPS SDRAM interface is compatible with the
interface of the soft SDRAM memory controller IPs and hard SDRAM memory
controllers in the FPGA fabric.
FPGA Configuration and Processor Booting
The FPGA fabric and HPS in the SoC FPGA are powered independently. You can
reduce the clock frequencies or gate the clocks to reduce dynamic power, or shut
down the entire FPGA fabric to reduce total system power.
You can configure the FPGA fabric and boot the HPS independently, in any order,
providing you with more design flexibility:
