Appeal No. 97-0609
Application 08/480,106
DECISION ON APPEAL
Appellants have appealed to the Board from the examiner’s
final rejection of claims 1 to 14, which constitute all the
claims in the application.
Representative claim 11 is reproduced below:
11. A method for dynamically handling processing errors
during processing of a stream of instructions in a computer
system having a plurality of functional units, comprising the
steps of:
detecting an error occuring during processing of an
operation subsumed by an instruction of said stream of
instructions by a functional unit;
determining that said error was caused by a timing dependent
defect by iteratively increasing an instruction processing cycle
time and retrying at least one operation; and
after said determining step, causing said functional unit to
process subsequent operations in said stream of instructions in a
degraded performance mode such that said error will not recur.
The following reference is relied on by the examiner:
Missios et al. (Missios) 4,025,768 May 24, 1977
Claims 1 to 14 stand rejected under 35 U.S.C. § 103. As
evidence of obviousness, the examiner relies upon Missios alone.
