2.2. Core Cache Interface (CCI-P) Interface

Table 3.   Core Cache Interface (CCI-P) Specifications
Parameter Value Notes
Width 512-bit CCI-P interface width.
Maximum CCI-P Frequency pClk -
Host Memory Cache-Line Size 64-byte -
Minimal write access size 1-byte

AFUs can write 1 byte to 63 bytes by setting the mode of TX channel 1 to a value of 1'b1

MMIO access width 32-bit and 64-bit 64-bit accesses are mandatory for Device Feature Header (DFH) enumeration.
MMIO Read Response Timeout 65536 clock cycles -
Virtual Channels Supported VH0, VA Accesses to VH0 and VA are mapped to the PCIe* link. Accesses to VH1 or VL0 are mapped to VH0.
