DMA Controller with AXI IP
Design IP
Overview

SmartDV’s DMA Controller with AXI IP is a silicon-proven solution designed to deliver high-bandwidth, low-latency data transfers with minimal processor overhead, ideal for automotive, industrial, and AI/ML applications. Fully compliant with the AMBA AXI3 and AXI4 protocols, it supports high-performance interconnects and enables efficient data movement between memory and high-speed peripherals in complex SoC designs.

Designed for flexibility, the IP core is highly configurable to meet specific design requirements, supporting both ASIC and FPGA implementations while optimizing for area, power, and performance. The controller supports multiple independent DMA channels with configurable priorities, support for scatter-gather and burst transactions, and address generation features for efficient memory management. Its advanced interrupt and error handling mechanisms ensure robust operation in safety-critical environments.

To align with automotive industry requirements, the DMA Controller IP supports ISO 26262 design flows and is suitable for ASIL-compliant systems, making it a reliable choice for applications like ADAS, EV control units, and domain controllers.

DMA Controller with AXI
Benefits
  • High-Performance DMA Engine – Supports 1 to 16 transmit and receive channels with full-duplex operation for concurrent read/write transfers
