6.2.1.5. Example (Recommended) System Memory Mapping Scheme

When using ECC, the FPGA (through FPGA-to-HPS ) memory map and the MPU memory map must match. During ECC calculations, all internal address bits are used, therefore, in order to prevent ECC Double Bit Error (DBE), the entire address used to access DDR memory must be the same for any master of that memory. Intel highly recommends using the following memory map, which is consistent for all memory spans.
