125 | help | |
126 | Unicore processors can not fetch/store information which is not | |
127 | naturally aligned on the bus, i.e., a 4 byte fetch must start at an | |
128 | address divisible by 4. On 32-bit Unicore processors, these non-aligned | |
129 | fetch/store instructions will be emulated in software if you say | |
130 | here, which has a severe performance impact. This is necessary for | |
131 | correct operation of some network protocols. With an IP-only | |
132 | configuration it is safe to say N, otherwise say Y. | |
