This program acknowledges the 2s full concomitant of an 8-bit number stored in retentivity location 3000H. ?? allow us wear upon that the operand stored at repositing location 3000H is 85H. ?? The operand is moved to collector from storehouse location 3000H. ?? Then, its complement is found by using CMA instruction. ?? One is added to accumulator by incrementing it to find its 2s complement. ?? The government issue is stored at memory location 3001H. Program (ii. a) Explanation ?? This program finds the 1s complement of 16-bit number stored in memory 3000H3001H. ?? in that location is no direct look to find 1s complement of 16-bit number.Therefore, this trick be accomplished by conclusion the 1s complement of two 8-bit numbers. ?? Let us put one over that the operand stored at memory locations 3000H-3001H is 45H-6AH. ?? The operand is loaded into H-L equ ate from memory locations 3000H-3001H. ?? The discredit-order is moved from say L to accumulator. ?? Its complement is found by using CMA instruction. ?? The prove obtained is moved back to annals L. ?? Then, the higher-order is moved from register H to accumulator. ?? Its complement is found by using CMA instruction. ?? The provide obtained is moved back to register H. ??Now, the utmost burden is in H-L coupling. 12 ?? The result is stored from H-L equalise to memory locations 3002H-3003H. Program (ii. b) Explanation ? ? ? ? ? ? ? ? ? ? ? ? ? This program finds the 2s complement of 16-bit number stored in memory locations 3000H- 3001H. There is no direct way to find 2s complement of 16-bit number. Therefore, this can be accomplished by finding the 1s complement of two 8-bit numbers and then incrementing it to get 2s complement. Let us assume that the operand stored at memory locations 3000H-3001H is 12H05H. The operand is loaded into H-L oppose from memory locations 3000H -3001H.The bring down-order is moved from register L to accumulator. Its complement is found by using CMA instruction. The result obtained is moved back to register L. Then, the higher-order is moved from register H to accumulator. Its complement is found by using CMA instruction. The result obtained is moved back to register H. H-L pair is incremented to get 2s complement. Now, the final result is in H-L pair. The result is stored from H-L pair to memory locations 3002H-3003H. 4.
