Assembly language Program (i. a) Program (i. b) 11 explanation This program finds the 2s complement of an 8-bit number stored in storage location 3000H. Let us assume that the operand stored at retrospect location 3000H is 85H. The operand is travel to accumulator from holding location 3000H. Then, its complement is prime by using CMA instruction. One is added to accumulator by incrementing it to find its 2s complement. The firmness of purpose is stored at storehouse location 3001H. Program (ii. a) comment This program finds the 1s complement of 16-bit number stored in memory 3000H3001H. There is no direct way to find 1s complement of 16-bit number.Therefore, this can be accomplished by finding the 1s complement of two 8-bit numbers. Let us assume that the operand stored at memory locations 3000H-3001H is 45H-6AH. The operand is pixilated into H-L pair from memory locations 3000H-3001H. The lower-order is moved from register L to accumulator. Its complement is arrange by using CMA instruction. The response obtained is moved jeopardize 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. Now, the final result is in H-L pair. 12 The result is stored from H-L pair 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 pair from memory locations 3000H-3001H.The lower-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 m oved 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.
