Tejun, The interface block is like this: AHB to AXI Bridge ------------------------------------------------------------------------------------------------------------- ---------------------------------- ---------------------------------------------- | AHB Slave | | AHB Master (DMA) | --------------------------------- ---------------------------------------------- ---------------------------------- ---------------------------------------------- | AHCI registers | | DMAC | ----------------------------------- ----------------------------------------------- I need to convert PCI interface to AHB. Has anyone done that before? Thanks Sagar On Fri, Feb 20, 2009 at 6:06 AM, Tejun Heo <tj@xxxxxxxxxx> wrote: > Sagar Borikar wrote: >> Hi Tejun >> >> Its not PCI interface but AHB.
