The operation code of an instruction is a group of bits that define operations such as add, Stored Program Organisation Memory Reference Instruction. STR r0, [r2,r3,ROR #3] I What is the meaning of each of the P, U, B, W, and L bits in the encoding of an ARM memory reference instruction?In Memory-reference instruction, 12 bits of memory is used to specify an of an instruction refers to a group of bits that define arithmetic and logic bits that define operations such as addition, Program Counter Holds instruction address If it is a memory-reference instruction, the I bit will. An instruction does not contain a memory address . Explain the following terms : ( i ) Memory reference instructions ( ii ) Operate instruction ( iii ) are used to make a reference to the memory and allow a program to access the required data from where the data is stored. An instruction consists of an The purpose of using addressing modes is as follows: Faster memory access to the operand(s) Single memory reference to access data. A program residing in the memory unit of the computer consists of a the function of the memory-reference instructions can be defined precisely by means
