Unicore processors can not fetch/store information which is not

naturally aligned on the bus, i.e., a 4 byte fetch must start at an

address divisible by 4. On 32-bit Unicore processors, these non-aligned
|

fetch/store instructions will be emulated in software if you say
|

here, which has a severe performance impact. This is necessary for

correct operation of some network protocols. With an IP-only
