- P. 2. Consider a proposed new instruction named rpt. This instruction combines a loop's condition check and counter decrement into a single instruction. For example rpt x29, loop would do the following: if (x29 >0) { x29 = x29 -1: goto loop a) If this instruction were to be added to the RISC-V instruction set. what is the most appropriate instruction format? b) What is the shortest sequence of RISC-V instructions that performs the same operation?d) This addressing mode is always used to access memory, shown here as the source operand of this instruction: LDR R1,[R0]?- The stack memory is addressed by a combination of the plus offset. The PUSH and POP instructions always transfer between segment -bit number the stack and a register or memory location in the 8086 microprocessors. For string instructions, DI always addresses data in the segment. The 8086 LOOP instruction decrements register for a 0 to decide if a jump occurs and tests it
