claims pending in the case.
The invention pertains to cache management mechanisms in a computer system. More
particularly, the cache management mechanism of the instant invention intelligently places preload
instructions into the instruction stream of a computer system such that, through identification of certain
instruction stream constructs, the cache memory gets the right information at the right time. These
instruction stream constructs, or predictor constructs, are used to predict the presence of two other
stream constructs, the first instruction stream construct predicted involving the loading of an address
(address generation construct), and the second instruction stream construct predicted involving the use
of the generated address to gain access to the associated information (data load construct).
Representative independent claim 1 is reproduced as follows:
1. A computer apparatus, said computer apparatus comprising:
a first central processing unit, said first central processing unit executing an instruction stream,
said instruction stream having a first preload instruction inserted therein, said first preload instruction
having been inserted by a compiler at a location proximate to a first predictor construct contained in
said instruction stream, said first preload instruction containing a first address for first information that
will be needed by said first central processing unit.
