Request Information

Product Description

The Northwest Logic DMA Back-End Core provides high-performance, scatter-gather DMA operation in a flexible fashion. This enables the core to be easily integrated and used in a wide variety of DMA-based systems. Using the core eliminates the need for the user to implement their own DMA design, significantly reducing development time and risk.

Note: Utilization numbers provided in the 'IP Implementation and Quality Metrics' tab is for a x1 lane DMA Back-End Core implementation

Key Features and Benefits
