DMA Controller with AHB
Design IP
Overview

SmartDV’s DMA Controller with AHB IP is a silicon-proven solution engineered to enable high-throughput, low-latency data transfers with minimal CPU overhead—making it ideal for data-intensive automotive applications such as ADAS, infotainment, and powertrain systems. Fully compliant with the AMBA AHB protocol, it integrates seamlessly into SoC architectures, delivering efficient communication between memory and on-chip or off-chip peripherals.

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 IP supports multiple independent DMA channels with programmable priority levels, round-robin or fixed-priority arbitration, and features like scatter-gather, burst transfer modes, and address increment control. It includes advanced interrupt handling and status reporting to facilitate real-time responsiveness and efficient processor interaction.

To meet the demands of functional safety, the DMA Controller IP supports ISO 26262 design flows, making it suitable for integration into ASIL-compliant automotive systems.
