Port Descriptions

Port Direction Width Domain Sense Handling if Unused Function
S_AXI_araddr Input ADDR_WIDTH S_AXI_clk NA Active ARADDR: The read address bus gives the initial address of a read burst transaction. Only the start address of the burst is provided and the control signals that are issued alongside the address detail how the address is calculated for the remaining transfers in the burst.
S_AXI_arburst Input 1 S_AXI_clk NA Active ARBURST: The burst type, coupled with the size information, details how the address for each transfer within the burst is calculated.
S_AXI_arcache Input 1 S_AXI_clk NA Active ARCACHE: Indicates the bufferable, cacheable, write-through, write-back, and allocate attributes of the transaction.
S_AXI_arid Input ID_WIDTH S_AXI_clk NA Active ARID: The data stream identifier that indicates different streams of data.
S_AXI_arlen Input 1 S_AXI_clk NA Active ARLEN: The burst length gives the exact number of transfers in a burst. This information determines the number of data transfers associated with the address.
S_AXI_arlock Input 1 S_AXI_clk NA Active ARLOCK: This signal provides additional information about the atomic characteristics of the transfer.
S_AXI_arprot Input 1 S_AXI_clk NA Active ARPROT: Indicates the normal, privileged, or secure protection level of the transaction and whether the transaction is a data access or an instruction access.

S_AXI_bvalid Output 1 S_AXI_clk LEVEL_HIGH Active BVALID: Indicates that the master is driving a valid transfer.
  • A transfer takes place when both BVALID and BREADY are asserted
S_AXI_clk Input 1 NA EDGE_RISING Active Slave Interface Clock: All signals on slave interface are sampled on the rising edge of this clock.
S_AXI_rdata Output DATA_WIDTH S_AXI_clk NA Active RDATA: The primary payload that is used to provide the data that is passing across the interface. The width of the data payload is an integer number of bytes.

S_AXI_rresp Output 1 S_AXI_clk NA Active RRESP: Indicates the status of the read transfer. The allowable responses are OKAY, EXOKAY, SLVERR, and DECERR.
S_AXI_rvalid Output 1 S_AXI_clk LEVEL_HIGH Active RVALID: Indicates that the master is driving a valid transfer.
  • A transfer takes place when both RVALID and RREADY are asserted
S_AXI_wdata Input DATA_WIDTH S_AXI_clk NA Active WDATA: The primary payload that is used to provide the data that is passing across the interface. The width of the data payload is an integer number of bytes.
S_AXI_wlast Input 1 S_AXI_clk LEVEL_HIGH Active WLAST: Indicates the boundary of a packet.
S_AXI_wready Output 1 S_AXI_clk LEVEL_HIGH Active WREADY: Indicates that the slave can accept a transfer in the current cycle.
S_AXI_wstrb Input DATA_WIDTH / 8 S_AXI_clk NA Active WSTRB: The byte qualifier that indicates whether the content of the associated byte of TDATA is processed as a data byte or a position byte. For a 64-bit DATA, bit 0 corresponds to the least significant byte on DATA, and bit 0 corresponds to the least significant byte on DATA, and bit 7 corresponds to the most significant byte. For example:
  • STROBE[0] = 1b, DATA[7:0] is valid
  • STROBE[7] = 0b, DATA[63:56] is not valid
S_AXI_wvalid Input 1 S_AXI_clk LEVEL_HIGH Active WVALID: Indicates that the master is driving a valid transfer.
  • A transfer takes place when both WVALID and WREADY are asserted
