DMA Controller
The DMA controller provides high-bandwidth data transfers for modules without integrated DMA
controllers. The DMA controller is based on the ARM Corelink
the following features:
• Micro-coded to support flexible transfer types
• Memory-to-memory
• Memory-to-peripheral
• Peripheral-to-memory
• Scatter-gather
• Supports up to eight channels
• Supports flow control with 31 peripheral handshake interfaces
• Software can schedule up to 16 outstanding read and 16 outstanding write instructions
• Supports nine interrupt lines: one for DMA thread abort and eight for external events

EMACs
The two EMACs are based on the Synopsys DesignWare 3504-0 Universal 10/100/1000 Ethernet MAC and
offer the following features:
• Supports 10, 100, and 1000 Mbps standard
• Integrated DMA controller
• Supports the PHY interfaces using the HPS I/O pins:
• Reduced gigabit media independent interface (RGMII)
• Supports the PHY interfaces using adaptor logic to route signals to the FPGA I/O pins:
• Media independent interface (MII)
• Gigabit media independent interface (GMII)
• Reduced gigabit media independent interface (RGMII)
• Serial gigabit media independent interface (SGMII) supported through the GMII to FPGA fabric
with additional external conversion logic
