Computing Architecture Last updated on 2008 1 10, a full moon day
Basically, an instruction is a combination of Flag Bit, Opcode, and Data. Flag Bit can be categorized into whether sign, or un-sign. Opcode is control. Opcode is also known as mnemonic. Opcode can be categorized into ALU oriented, General purpose oriented, Streaming Data oriented, and ... ; Data can be either being inside of Data bits of the instruction, or sometime can be a whole word of bits as Data.

Depending on hardware specifications, computing architecture varies. i.e. super computer specification uses not only instruction diagram, but also vector diagram. In addition to instruction diagram and vector diagram, Quantum computer specification uses particle diagram, and etc.
