EXAMPLE 1 Instruction Memory’s file: 5th_fig421_MemEx1/inst.rom The user should set initial register values (linear). No data values are required. Description: A simple sequence of five “add” instructions with no hazards. ADD r1,r1,r2 ADD r3,r0,r2 ADD r4,r0,r2 ADD r5,r0,r2 ADD r6,r0,r2 ADD r1,r1,r2 – type R instruction opcode = 0 rs = 1 rt = 2 rd = 1 000000 00001 00010 00001 0x00220820 sh = 0 func = 32 00000 100000 ADD r3,r0,r2 – type R instruction opcode = 0 rs = 0 rt = 2 rd = 3 000000 00000 00010 00011 0x00021820 sh = 0 func = 32 00000 100000 ADD r4,r0,r2 – type R instruction opcode = 0 rs = 0 rt = 2 rd = 4 000000 00000 00010 00100 0x00022020 sh = 0 func = 32 00000 100000 ADD r5,r0,r2 – type R instruction opcode = 0 rs = 0 rt = 2 rd = 5 000000 00000 00010 00101 0x00022820 sh = 0 func = 32 00000 100000 ADD r6,r0,r2 – type R instruction opcode = 0 rs = 0 rt = 2 rd = 6 000000 00000 00010 00110 0x00023020 sh = 0 func = 32 00000 100000 The hexadecimal code example is: ADD r1,r1,r2 – 0x00220820 ADD r3,r0,r2 – 0x00021820 ADD r4,r0,r2 – 0x00022020 ADD r5,r0,r2 – 0x00022820 ADD r6,r0,r2 – 0x00023020 Calculations check (with linear initial register values): ADD r1,r1,r2 – r1 = 3 ADD r3,r0,r2 – r3 = 2 ADD r4,r0,r2 – r4 = 2 ADD r5,r0,r2 – r5 = 2 ADD r6,r0,r2 – r6 = 2
