The R3000 utilizes a variable-sizeinstruction and data cache that operates in write-through mode. Cacheline size also varies. Cache tags may be invalidated on a per-word basisby execution of a byte write to a specified word while the cache isisolated. See also the manual entry for cacheR3kLib.<p>For general information about caching, see the manual entry for cacheLib.<p></blockquote><h4>INCLUDE FILES</h4><blockquote><p><b>cacheLib.h</b><p></blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./cacheR3kALib.html#top">cacheR3kALib</a></b>, <b><a href="./cacheR3kLib.html#top">cacheR3kLib</a></b>, <b><a href="./cacheLib.html#top">cacheLib</a></b>, Gerry Kane:<i>MIPS R3000 RISC Architecture </i><hr><a name="cacheR3kDsize"></a><p align=right><a href="rtnIndex.html"><i>Libraries : Routines</i></a></p></blockquote><h1><i>cacheR3kDsize</i>( )</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote> <p><strong><i>cacheR3kDsize</i>( )</strong> - return the size of the R3000 data cache</p></blockquote><h4>SYNOPSIS</h4><blockquote><p><pre>ULONG cacheR3kDsize (void)</pre></blockquote><h4>DESCRIPTION</h4><blockquote><p>This routine returns the size of the R3000 data cache.
