1. A method for analyzing the effectiveness of a computer
cache, the method comprising the following steps:
(a) monitoring addresses on an interconnect;
(b) capturing, in a memory, a subset of the addresses;
(c) repeating steps (a) and (b) multiple times, where at
least two of the subsets of the addresses are different;
(d) applying the captured addresses to a model of the
computer cache; and
(e) computing statistical cache data, for the model, for the
captured addresses.

THE REJECTION
Claims 1, 3-5 and 7-12 stand rejected under 35 U.S.C. § 103
as being unpatentable over Colglazier in view of Chen.
OPINION
We reverse the aforementioned rejection. We need to address
only the independent claims, i.e., claims 1, 4, 8 and 10.
Claim 1 requires monitoring addresses on an interconnect,
capturing, in a memory, a subset of the addresses, and repeating
the monitoring and capturing multiple times, where at least two
