Appellants’ invention relates to a data processing device. An understanding of
the invention can be derived from a reading of exemplary claim 1, which is reproduced
below.
1. A data processing device comprising:
an instruction decoder for sequentially decoding a plurality of
instructions described in a program sequence and outputting control
signals respectively corresponding to the instructions, and
an instruction execution unit for executing operations respectively
designated by said plurality of instructions in accordance with said control
signal output from said instruction decoder, wherein
said instruction decoder decodes a first instruction among said
plurality of instructions and outputs a first control signal in a first period;
said instruction execution unit executes the operation designated by
said first instruction in accordance with said first control signal in a second
period succeeding to said first period;
said instruction decoder outputs a second control signal in a third
period by decoding a second instruction of which operation is executed
under a predetermined condition among said plurality of instructions; and
said instruction execution unit determines whether or not said
predetermined condition is satisfied in a fourth period and executes the
operation designated by said second instruction in response to a result of
the determination, said fourth period being started after elapsing a same
time as said second period or longer from an ending of said third period.
The prior art of record relied upon by the examiner in rejecting the appealed
