Hi ! I have updated the WISHBONE DMA specification and created a web page for the project (See SoC ...). Therefore the location for the DMA spec has changed ! The new location is: http://www.opencores.org/cores/wb_dma/dma_doc.pdf I have uploaded revision 0.4 of the specification and started coding the DMA. I would appreciate thorough review of the spec ! Thanks a lot ! rudi
