18 years agoMore specs on 'PCI Express High Perf Ref Dsgn' AN 456
Hello,
Are there any documents that give further elaboration on the 'PCI Express High Performance Reference Design' (Application Note 456)? Specifically, I am looking for a register description of the DMA control registers. AN 456 does a good job of explaining the general flow of operation, but does not give offsets for the important DMA control registers that would allow an application programmer to write a driver against. My goal is to write a Linux driver that uses the dev board reference design. In the end, I will have to modify the driver and reference design to fit my own project. Thanks.2 Replies

The High Performance reference design uses the Chaning DMA Example Design that is provided with PCI Express Compiler. See Chapter 7 of the pci express compiler user guide (http://www.altera.com/literature/ug/ug_pci_express.pdf) for a description of the registers used in this design.

The register description is just what I needed. Thanks for the reply.
