Types of instruction in computer architecture

Arithmetic Instructions; Branch Instructions; Data Transfer Instructions; Logic Instructions; Bit-oriented Instructions. The first part of each instruction, In computer architecture , the instruction formats can be classified into two main groups . The first type is based on the number of operands present into theIn computer science, an instruction set architecture (ISA), also called computer architecture, is an abstract model of a computer. There are four different types of operands that can appear in an instruction: – Direct operand - an operand stored in the register or in the memory location Memory - reference instruction; Register - reference instruction; Input-Output instruction.
