pci_t32 core & DMA

Hi ! 

I want to design a data aquisition system using pci interface.I have planned to use pci_t32 IP core but I have to use DMA propherty.I know master core supplies dma propherty but I am not sure whether target cores supply or not ? Could you help me about it ? Should I use only target core or master/target core like pci_mt32
