Description

|
AXI
|
The generic term for all implemented AXI protocol interfaces.
|
|
master device or connected master
|
An IP core or device (or one of multiple interfaces on an IP core) that generates AXI transactions out from the IP core onto the wires connecting to a slave device.
|
|
slave device or connected slave
|
An IP core or device (or one of multiple interfaces on an IP core) that receives and responds to AXI transactions coming in to the IP core from the wires connecting to a master device.
|
|
master interface (generic)
|
An interface of an IP core or module that generates out-bound AXI transactions and thus is the initiator (source) of an AXI transfer. On AXI master interfaces, AWVALID, ARVALID, and WVALID are outputs, and RVALID and BVALID are inputs.
|
|
slave interface (generic)
|
An interface of an IP core or module that receives in-bound AXI transactions and becomes the target (destination) of an AXI transfer. On AXI slave interfaces, AWVALID, ARVALID, and WVALID are inputs, and RVALID and BVALID are outputs.
|
|
SI-side
|
A module interface closer to the SI side of the AXI SmartConnect core.
|
|
MI-side
|
A module interface closer to the MI side of the AXI SmartConnect core.
|
|
upsizer
|
Data width conversion function in which the datapath width gets wider when moving in the direction from the SI-side toward the MI-side (regardless of write/read direction).
|
|
downsizer
|
Data width conversion function in which the datapath width gets narrower when moving in the direction from the SI-side toward the MI-side (regardless of write/read direction).
