Appeal No. 94-3053
Application 07/832,661
circuit to monitor another processor on a semiconductor chip.
The serial scan circuit is used to set the invention’s proces-
sor to particular predetermined conditions and then check the
chip’s
processor for the existence of such conditions. When a
predetermined condition is met, the invention’s processor
controls the operation of the monitored processor.
Independent claim 55 is reproduced as follows:
55. A data processing device comprising:
a semiconductor chip;
an electronic processor on-chip;
an on-chip condition sensor connected to said
electronic processor for analysis of the operations
thereof, including means for recognizing the
occurrence of a predetermined condition during real
time operation of said electronic processor and
means responsive to the recognition of said
predetermined condition for applying a control input
to said electronic processor during said real time
operation thereof; and
a serial scan circuit connected to said on-chip
condition sensor for inputting to said on-chip
condition sensor control information which causes
