Abstract
An instruction processing apparatus is composed of a main memory for storing user instructions and an instruction control section with a control store addressed by a user instruction read out from the main memory. The main memory stores a high performance instruction with the same function as that of a set of low performance instructions, in addition to ordinary user instructions (low performance instructions). The instruction control section includes a first control store which is addressed by a high performance instruction from the main memory and stores a first microprogram with the same format and function as those of a set of the low performance instructions to form a high performance instruction, and a second control store which is addressed by the output of said first control store and a low performance instruction from the main memory and stores a second microprogram to form a low performance instruction.
