The Northwest Logic AXI DMA Back-End Core offered by Rambus provides high-performance, scatter-gather DMA operation in a flexible fashion. This enables . ....
High-performance PCIe-AXI Bridge and/or scatter-gather DMA The Northwest Logic Expresso DMA Bridge Core from Rambus provides high-performance DMA and/or bridging between PCI Express and AXI for both Endpoint and Root Port applications. Key features include: DMA operation hard cores • Supports memory-mapped/streaming (FIFO) DMA operation • Can be configured with multiple DMA Channels which are independently controlled by software • Supports legacy, MSI, MSI-X and local AXI interrupts Using the core eliminates the need for the user to implement their own DMA and/or bridging design thus significantly reducing development time and risk. Linux Expresso DMA Drivers. The Expresso DMA Driver works ....
DMA Back-End Core The Northwest Logic DMA Back-End Core from Rambus 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. Key features which contribute to this flexibility include: • Works with Northwest Logic soft Expresso Cores and FPGA hard cores • Can be configured with multiple independent DMA Engines which each have their own user interface • Supports Packet/Block and Addressed/Non-addressed transfers • Supports host –based and local descriptors • Supports legacy, MSI, MSI-X interrupts Using the core eliminates the need for the user to implement their own DMA design significantly reducing development time and risk. ....
