Querry Regarding Memory Alignment

[Vishwas Srivastava]

Hi All,

            I have  2 questions regarding memory access/alignment
1: can aligned/unaligned virtual address could translate to
unaligned/aligned physical address ? or
 aligned virtual --- > aligned phy and unaligned virtual --- > unaligned
phy ??
2: Since the cpu access the memory in word size, for a large buffer, (say
size N bytes where N > wordsize) isn't it sufficient for buffer to be
properly aligned if its address % WORD_SIZE == 0? rather than address % N
== 0  check??
Since cpu, anyways will not access more than word size at a time so any
address which is divisible by wordsize is by default properly aligned from
the cpu access point of view?


Please share your inputs.
