LogiCORE IP AXI System ACE Interface Controller (axi_sysace) (v1.01.a)
AXI System ACE Interface Controller Design Parameters
To allow the designer to obtain a AXI SYSACE core that is uniquely tailored for the designer’s system, certain
features can be parameterized. Some of these parameters control the interface to the AXI interface module while
others provide information to minimize resource utilization. The features that can be parameterized in the AXI
SYSACE are shown in Table 4.
In addition to the parameters listed in this table, there are also parameters that are inferred for each AXI interface in
the EDK tools. Through the design, these EDK-inferred parameters control the behavior of the AXI Interconnect.
For a complete list of the interconnect settings related to the AXI interface, see DS768, AXI Interconnect IP Data Sheet.

Note:
1. The range specified by C_BASEADDR and C_HIGHADDR must be sized and aligned to some power of 2, 2n. Then, the n least
significant bits of C_BASEADDR is zero. This range needs to encompass the addresses needed by the AXI SYSACE registers
2. See Xilinx DS080, System ACE Compact Flash Solution, for more information.
Allowable Parameter Combinations
The address-range size of the AXI System ACE Interface Controller must be a power of 2. If the desired
address-range size is represented by 2n, then the n least significant bits of the base address must be 0.
C_BASEADDR and C_HIGHADDR must specify an address range whose size is at least 0x80 bytes, to cover the
addressable registers and data buffer available in the Xilinx System Ace Compact Flash chip.
