Reason:? This program discovers the 2’s complement of your 8-bit number stored in recollection location 3000H.? Let us assume that the operand stored in memory position 3000H is definitely 85H.? The operand is usually moved to accumulator from memory space location 3000H.? Then, its complement is found by using CMA instruction.? Is added to accumulator by incrementing it to look for its 2’s complement.? In this way stored for memory location 3001H. Plan (ii. a): Explanation:? This program finds the 1’s match of 16-bit number stored in memory 3000H3001H.? There is no immediate way to look for 1’s complement of 16-bit number.

Therefore , this can be accomplished by finding the 1’s complement of two 8-bit numbers.? Let us assume that the operand stored at memory locations 3000H-3001H is 45H-6AH.? The operand is filled into H-L pair coming from memory places 3000H-3001H.? The lower-order is definitely moved via register D to accumulator.? Its enhance is found by utilizing CMA instruction.? The result acquired is relocated back to sign-up L.? In that case, the higher-order is moved from enroll H to accumulator.? Its complement is located by using CMA instruction.? The effect obtained is definitely moved returning to register H.?

Now, a final result is at H-L pair. 12? The result is stored by H-L match to recollection locations 3002H-3003H. Program (ii. b): Justification:??????? This program locates the 2’s complement of 16-bit amount stored in recollection locations 3000H- 3001H.

You read ‘Ece Lab Manual Ece 315’ in category ‘Essay examples’ There is no immediate way to look for 2’s match of 16-bit number. Therefore , this can be accomplished by finding the 1’s complement of two 8-bit numbers and after that incrementing that to get 2’s complement. Let us assume that the operand stored in memory spots 3000H-3001H is definitely 12H05H. The operand is loaded in to H-L set from recollection locations 3000H-3001H.

The lower-order is relocated from signup L to accumulator. Its complement is found by using CMA instruction. The effect obtained can be moved returning to register D. Then, the higher-order is usually moved from register H to accumulator. Its go with is found by making use of CMA training. The result obtained is moved back to enroll H. H-L pair can be incremented to get 2’s complement. Right now, the final result is in H-L pair. In this way stored by H-L couple to memory locations 3002H-3003H. 4.
