The factorization algorithm factorizes out code containing branches, allows macros to be defined in terms of other macros, and permits the use of two bytes for defining a macro instruction code.
As can be seen from those figures, the processor is divided into six major sections: the instruction bus interface (including an instruction prefetch buffer), the macro instruction unit, the instruction control unit, the floating point unit, the integer execution unit, and the data bus interface.
A multiplexor (MUX) that can accept instructions from either the instruction buffer or the Macro Instruction ROM and feed them to the instruction control unit is also associated with the instruction bus interface.
