Chapter 3: Hardware Design
Stream Pipes Control and Status Registers
The register sets in the design are available under the user_axilite_control block. The block
has an AXI4-Lite interface through which the registers can be accessed. In the current
implementation, the base address of the user_axilite_control is 0xB005_0000. Table 3-1 lists
the registers that are available currently.
GPIO Selection
Table 3-2 provides the list of GPIOs for channel control, memory loopback reset, and IQ
selection.
