The tables in this appendix list the Cortex-R7 MPCore processor signals, with their direction, either input or output, and a high-level description.
Many signal names end with [N:0]. The value of N is one less than the number of processors in your design.
There is no link between the number of processors in a design and the number of AXI masters in a design. A single processor design can have one or two AXI master ports.
