The method may include, in response to initiation of a transfer of a datum by a current instance of an initiating task: creating at least one DMA descriptor describing the DMA transfer expected for said datum; inserting DMA descriptors into a list of descriptors awaiting processing by a DMA ...
DATA TRANSFER CONTROLLER AND DATA TRANSFER METHOD PROBLEM TO BE SOLVED: To provide a DMA controller (data transfer controller) for increasing a DMA transfer speed while reducing loads to be applied to a CPU. SOLUTION: In registers SREG1, SREG2 and EREG1, EREG2, two pairs of start addre.....

Method and apparatus for converting address information between PCI bus protocol and a message-passing queue-oriented bus protocol A work queue entry is created with the remainder of the PCI address and a pointer to the DMA data. An RDMA operation is used to perform the DMA transfer. The page...
The AXI Datamover is a key Interconnect Infrastructure IP which enables high throughput transfer of data between AXI4 memory mapped domain to AXI4-Stream domain. The AXI Datamover provides MM2S and S2MM AXI4-Stream channel which operate independently in a full duplex like method. The AXI Datamov...
PIO, on the other hand, involves the host or EP directly reading or writing data to/from the PCIe configuration or I/O space registers of the target device. This method is typically used for control and configuration purposes rather than large data transfers. PIO operations are not exp...
providing a means for deciding and transferring the total number of data units constituting a block, a means for updating the total number of the data units at the time of transfer and a means for issuing a bus request concerning the transfer of the subsequent data units before transfer ...
