HPS Features

The HPS consists of a dual-core ARM Cortex-A9 MPCore processor, a rich set of peripherals, and a shared

multiport SDRAM memory controller, as shown in the following figure.

System Peripherals and Debug Access Port

Each Ethernet MAC, USB OTG, NAND flash controller, and SD/MMC controller module has an integrated

DMA controller. For modules without an integrated DMA controller, an additional DMA controller module

provides up to eight channels of high-bandwidth data transfers. Peripherals that communicate off-chip are

multiplexed with other peripherals at the HPS pin level. This allows you to choose which peripherals to

interface with other devices on your PCB.

The debug access port provides interfaces to industry standard JTAG debug probes and supports ARM

CoreSight debug and core traces to facilitate software development.
