handle_write_data_ready() tasks to handle the handshake AWREADY, ARREADY and
WREADY signals, respectively.
The Advanced Slave API is capable of handling pipelined transactions. Pipelining can occur
when a transaction starts before a previous transaction has completed. Therefore, a write
transaction that starts before a previous write transaction has completed can be pipelined.
Figure 6-8 shows the write channel with three concurrent write_trans transactions, whereby the
get_write_addr_phase[2], get_write_data_burst[1] and execute_write_response_phase[0] are
concurrently active on the write address, data and response channels, respectively.
Similarly, a read transaction that starts before a previous read transaction has completed can be
pipelined.
Figure 6-8 shows the read channel with two concurrent read_trans transactions,
whereby the get_read_addr_phase[1] and execute_read_data_burst[0] are concurrently active
on the read address and data channels, respectively.
