Processing-in-memory control method for efficient instruction processing and computing device applying same

A processing-in-memory control method for efficient instruction processing in a processing-in-memory, the method comprising:

• determining a number of operands required when an instruction is processed;
• performing a memory WRITE when the number of required operands is zero and the instruction is a WRITE instruction;
• performing a memory READ once and responding to READ when the number of required operands is one and the instruction is a READ instruction;
• performing a memory READ once and performing a memory WRITE when the number of required operands is one and the instruction is not a READ instruction;
• performing a memory READ twice and performing a memory WRITE when the number of required operands is two;
• and
• performing a memory READ n times and performing a memory WRITE when the number of required operands is n.

A processing-in-memory computing device for efficient instruction processing in a processing-in-memory, the device comprising:

• an instruction interpretation processor configured to determine the number of operands required for instruction processing;
• a first memory read processor configured to be performed when the number of required operands is either one or two by instruction interpretation;
• a read response processor configured to be performed when the number of required operands is one and the instruction is a READ instruction;
• a second memory read processor configured to be performed when the number of required operands is two;
• an n-th memory read processor configured to be performed when the number of required operands is three (here, n is a natural number of three or greater);
• an instruction processor configured to be performed when the number of required operands is one and the instruction is not a READ operation or when the number of required operands is two or more;
• and
• a memory write processor configured to be performed when the number of required operands is one except for a READ operation.
