Processor, processor operation method and electronic device comprising same for selective instruction execution based on operand address

A processor comprising:

• a data-buffer configured to store an operand;
• a configuration-buffer configured to store address information of the operand;
• and
• a processing unit configured to identify an instruction for instructing execution of a first operation and address information of the operand corresponding to the instruction, and execute the instruction based on whether or not the address information of the operand satisfies a predetermined condition,
• wherein the processing unit is configured to:
• execute a second operation set for the instruction on the operand if the address information of the operand satisfies the predetermined condition;
• execute the first operation on the operand if the address information of the operand does not satisfy the predetermined condition,
• store a round counter and a round-key pointer which are used in an operation of the processor in a data-buffer in the processor and,
• store address information of the round counter and address information of the round-key pointer in a configuration-buffer in the processor.

An electronic device comprising:

• a memory configured to store an instruction and an operand corresponding to the instruction;
• and
• a processor configured to execute the instruction,
• wherein the processor comprises:
• a buffer configured to store the operand and address information of the operand received from the memory to execute the instruction;
• and
• a processing unit configured to identify the instruction for instructing execution of a first operation and the address information of the operand corresponding to the instruction, and execute the instruction based on whether or not the address information of the operand satisfies a predetermined condition, and
• the processing unit is configured to:
• execute a second operation set for the instruction on the operand if the address information of the operand satisfies the predetermined condition;
• and
• execute the first operation on the operand if the address information of the operand does not satisfy the predetermined condition;
• store a round counter and a round-key pointer which are used in an operation of the processor in a data-buffer in the processor and,
• store address information of the round counter and address information of the round-key pointer in a configuration-buffer in the processor.
