Operands residing in processor register are specified with a register address.Computers may have instructions of several different lengths containing varying number of addresses.
Post fix Notation.Attention reader! In the RISC processors, there are relatively few instructions and few addressing modes.

Generally CPU organization are of three types on the basis of number of address fields:In first organization operation is done involving a special register called accumulator. OR
Simple Instruction Format (using two addresses) Instruction Cycle State Diagram.
The bits that define the mode field of an instruction code specify a variety of alternatives for choosing the operands from the given address.
perfect preparation. These field contains different information as for computers every thing is in 0 and 1 so each field has different significance on the basis of which a CPU decide what to perform. OR
Operation specified by an instruction is executed on some data stored in the processor register or in the memory location. In this article, we will discuss different types of problems based on instruction format which are asked in GATE. OR each format consist of 16bits.
