ABSTRACT:
Peer-to-peer Direct Memory Access (DMA) permits the efficient transfer of data from one DMA capable Application Specific Integrated Circuit (ASIC) block to another without accessing memory. The peer-to-peer transfer can be done over a standard AMBA AHB bus architecture without side band signals and without violating the AHB specification.
