However, in many cases, blocks transferred to and from memory are stored in
sequential addresses, so repeatedly sending the address for each 4 bytes is
unnecessary. With data streaming transfers, the initial address is sent, and then
the blocks of data are sent; it is then assumed that the data requests are
sequential. Figure 8 shows 40 MBps data streaming in operation.
