A large memory area with 2 Mbyte (256 k × 32-bit [doubleword]) is to be checked in the background of CPU. CRC is to be performed every 1 Kbyte (128 doubleword). Therefore there will be 2048 pre-recorded CRC values. For illustration purpose, we map MCRC_CRC_REGL1 register to DMA channel 1 and MCRC_PSA_SIGREGL1 register to DMA channel 2. Let’s assume all DMA transfers are carried out in 64-bit transfer size.
