When we are using multiple general-purpose registers, instead of a single accumulator register, in the CPU Organization then this type of organization is known as General register-based CPU Organization. In this type of organization, the computer uses two or three address fields in their instruction format
What is a general purpose register?
General purpose registers are used to store temporary data within the microprocessor . ... It is of 16 bits and is divided into two 8-bit registers BH and BL to also perform 8-bit instructions.
