memory resident on the control card is used to collect event
records from the target processor(s) for transfer to one or
more host systems for post processing of event data. The
control card includes a network interface to facilitate
communication between the host computer(s) used for post
processing of event data and to control, communicate with
and access the control card.
With the above discussion in mind, we find that the
combination of Bunnell and Roeber does not teach the claimed
invention. We find that Bunnell teaches a device for monitoring
CPU accesses to the main memory (22). Particularly, Bunnell
teaches a CPU (28) and a cache memory (30) connected to a CPU
activity monitor (24) via a cache miss signal (36). Whenever the
CPU requests data, the cache memory checks its internal memory
for the requested data. If the data is not available in the
cache, it issues a miss signal, and the CPU accesses the main
memory for the requested data. Bunnell also teaches that the CPU
activity monitor receives a clock signal, a cache miss signal and
a plurality of modes signals to determine when the CPU
transitions from an active to an inactive state and vice-versa.
Next, we find that Roeber teaches an event logging mechanism
having a central memory for storing user-designated events data
and time-stamps associated therewith. It is our view that one of
ordinary skill in the art would have duly realized that Roeber’s
