5.3.1.3. EMIF traffic patterns (for IO96B architecture)
Traffic programs for External Memory Interfaces (EMIF) IP's AXI interface for devices with IO96B I/O architecture.
Detailed Description
-
A "full" access uses the minimum AXI burst-length that fully utilizes all beats in the DRAM's burst access.
-
A "partial" access does not utilize all beats in the DRAM's burst and hence can trigger byte-enables (on the DM pins, if enabled) or read-modify-write (only applies to DDR5).
-
Some EMIF configurations can result in inaccesible address regions (ex: In-Line ECC reserves the upper 1/8th of the address space). The traffic programs auto-adapt to access the legal address space.
