This option replaces implementations of functions from ROM: - memcpy - memcmp - memmove - str[n]cpy - str[n]cmp The functions used in the firmware will be better optimized for misaligned memory. Here are some measurements in CPU cycles for 4096-byte buffers: memcpy: 28676 -> 4128 memcmp: 49147 -> 14259 memmove: 33896 -> 8086 strcpy: 32771 -> 17313 strcmp: 32775 -> 13191
