These are 2 completely unrelated products from Synopsys, see:
 a) https://www.synopsys.com/dw/ipdir.php?ds=amba_ahb_dma
 b) https://www.synopsys.com/dw/ipdir.php?ds=amba_axi_dma

I'm afraid not. Synopsys customers may get DW AXI DMAC databook here:
https://www.synopsys.com/dw/doc.php/iip/DW_axi_dmac/latest/doc/DW_axi_dmac_databook.pdf

Just a side note "DW" prefix stands for DesignWare and applicable
to most if not all IP libs from Synopsys so here we're talking about
AHB DMAC vs AXI DMAC. Still my understanding is different bus type is
not the one and only difference but just the one which might simplify
selection of one or another IP block.
