! Fast SH memcpy
|
||||
!
|
||||
! by Toshiyasu Morita (tm@netcom.com)
|
||||
! hacked by J"orn Rernnecke (joern.rennecke@superh.com) ("o for o-umlaut)
|
||||
! SH5 code Copyright 2002 SuperH Ltd.
|
||||
!
|
||||
! Entry: ARG0: destination pointer
|
||||
! ARG1: source pointer
|
||||
! ARG3: byte count
|
||||
!
|
||||
! Exit: RESULT: destination pointer
|
||||
! any other registers in the range r0-r7: trashed
|
||||
!
|
||||
! Notes: Usually one wants to do small reads and write a longword, but
|
||||
! unfortunately it is difficult in some cases to concatanate bytes
|
||||
! into a longword on the SH, so this does a longword read and small
|
||||
! writes.
|
||||
!
|
||||
! This implementation makes two assumptions about how it is called:
|
||||
!
|
||||
! 1.: If the byte count is nonzero, the address of the last byte to be
|
||||
! copied is unsigned greater than the address of the first byte to
|
||||
! be copied. This could be easily swapped for a signed comparison,
|
||||
! but the algorithm used needs some comparison.
|
||||
!
|
||||
! 2.: When there are two or three bytes in the last word of an 11-or-more
|
||||
! bytes memory chunk to b copied, the rest of the word can be read
|
||||
! without side effects.
|
||||
! This could be easily changed by increasing the minumum size of
|
||||
! a fast memcpy and the amount subtracted from r7 before L_2l_loop be 2,
|
||||
! however, this would cost a few extra cyles on average.
|
||||
! For SHmedia, the assumption is that any quadword can be read in its
|
||||
! enirety if at least one byte is included in the copy.
|
||||
