Generally instructions refer either memory addresses or registers to take data to perform operations on and in this case, the instructions refer registers for data and so are called Register Reference Instructions. Instructions have been divided on the basis of their reference and their functionality, into three main categories as
30 Jan 2014 Internal registers include the instruction register (IR), memory buffer register (MBR), memory data register (MDR), and memory address register (MAR). The instruction An address register contains memory addresses, which reference different blocks of memory within the system RAM. Many CPUs now
Register are used to quickly accept, store, and transfer data and instructions that are being used immediately by the CPU, there are various types of Registers those are used for various purpose. Among of the some Mostly used Registers named as AC or Accumulator, Data Register or DR, the AR or Address Register,
The operation code of an instruction is a group of bits that define operations such as addition, subtraction, shift, complement, etc. • An instruction must also include one or more operands, which indicate the registers and/or memory addresses from which data is taken or to which data is deposited.
6 Nov 2016 An instruction that has register operands therefore is a register-referencing instruction. An instruction that has memory operands therefore is a memory-referencing instruction. A single instruction can reference both registers and memory.
Register-reference Instructions. All take 1 clock cycle during execute; Skip means increment the PC; Complement can be calculated by subtracting each digit from the highest digit in the base. (base 2 just toggle, base 16 subtract from FFFF); CIL, CIR are logical shifts left or right with the extended accumulator (E) substituted

These instructions executed at timing cycle T3. Moreover, The first seven register-reference instructions perform clear, complement, circular shift, and increment microoperations on the AC or E registers. The next four instructions cause a skip of the next instruction in sequence when the condition satisfied. Also, The skipping
