  • Multi-Channel Streaming DMA Controller
    • The MC-SDMA IP core implements a highly configurable, bandwidth-efficient, and easy-to-use Direct Memory Access (DMA) controller that transfers data between the host system’s memory and multiple peripherals equipped with streaming interfaces.
    • The core interfaces with the host memory via a manager AMBA® AXI4 (memory-mapped) port and provides access to its configuration and status registers (CSRs) via a subordinate AXI4-Lite or APB4 interface.

  • AXI4 to/from AXI4-Stream DMA
    • The AXI4-DMA IP core implements a Direct Memory Access (DMA) engine that efficiently moves data between AXI4-Stream peripherals and a memory-mapped AXI4 bus.
    • The core implements two independent paths: One transfers data from the read manager memory-mapped interface to the manager stream (MM2S) interface.

  • AXI4 to/from AXI4-Stream Scatter-Gather DMA
    • The AXI4-SGDMA IP core implements a Host-to-Peripheral (H2P), or a Peripheral-to-Host (P2H) Direct Memory Access (DMA) engine, which interfaces the host system with an AXI4 Memory-Mapped master port and the peripheral with either a slave or a master AXI4-Stream port.
    • The core operates in either Scatter-Gather (SG) Mode, reading descriptors from a run-time defined memory mapped-location, or in Direct Mode, transferring data according to a descriptor stored in local registers.

  • Stream Direct Memory Access (SDMA)
    • The multi-channel Stream Direct Memory Access (SDMA) controller IP core provides high bandwidth direct memory access between memory and any IP peripherals with an AXI4-Stream interface for up to 16 channels.
    • The SDMA IP utilities a dedicated Write and Read circular buffer structure for data and descriptor(s) for each DMA channel, which helps in offloading data movement tasks from the Central Processing Unit (CPU) in processor-based systems.
