The contents of the transaction record are defined in Table 2-1 .
Table 2-1. Transaction Fields
Transaction Field Description
Protocol Transaction Fields
addr A bit vector (the length is equal to the ARADDR/AWADDR
signal bus width) containing the starting address of the first
transfer (beat) of a transaction. The addr value is transferred
over the ARADDR or AWADDR signals for a read or write
transaction, respectively.
prot An enumeration containing the protection type of a transaction.
The types of protection are:
AXI4_NORM_SEC_DATA (default)
AXI4_PRIV_SEC_DATA
AXI4_NORM_NONSEC_DATA
AXI4_PRIV_NONSEC_DATA
AXI4_NORM_SEC_INST
AXI4_PRIV_SEC_INST
AXI4_NORM_NONSEC_INST
AXI4_PRIV_NONSEC_INST
The prot value is transferred over the ARPROT or AWPROT
signals for a read or write transaction, respectively.
data_words A bit vector (of length equal to the greater of the
RDATA/WDATA signal bus widths) to hold the data words of
the payload. A data_words is transferred over the RDATA or
WDATA signals per beat of the read or write data channel,
respectively.
write_strobes A bit vector (of length equal to the WDATA signal bus width
divided by 8) to hold the write strobes. A write_strobes is
transferred over the WSTRB signals per beat of the write data
channel.
resp An enumeration to hold the response of a transaction. The types
of response are:
AXI4 _OKAY;
AXI4 _SLVERR;
AXI4 _DECERR;
A resp is transferred over the RRESP signals per beat of the
read data channel, and over the BRESP signals for a write
transaction, respectively.
