|
||
to addresses, each of which is separated from the last by a constant
|
||
interval called the <span class="firstterm">stride length</span>.
|
||
These can be a worst-case access pattern for the standard memory-caching
|
||
schemes when the stride length is a multiple of the cache line size.
|
||
Strided references are often generated by loops through an array, and (if
|
||
your data is large enough that access-time is significant) it can be
|
||
worthwhile to tune for better locality by inverting double loops or by
|
||
partially unrolling the outer loop of a loop nest. This usage is
|
||
borderline techspeak; the related term <span class="firstterm">memory
|
||
stride</span> is definitely techspeak.</p></dd><div class="navfooter"><hr/><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="STR.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="../S.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="stroke.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">STR </td><td width="20%" align="center"><a accesskey="h" href="../index.html">Home</a></td><td width="40%" align="right" valign="top"> stroke</td></tr></table></div></body></html>
