Question

This has to be in MSP430 assembly language. Thank you!

Here is a link with instructions set for msp430 (pages 5-8): https://www.ti.com/sc/docs/products/micro/msp430/userguid/as_5.pdf

Name: Grade: 101 1) Write an MSP430 assembly language subroutine, REP FREE, to examine the elements of a list of positive word-size numbers stored at location LIST IN. The list is already sorted in ascending order. The first element is the number, n, which is the length of the array. The subroutine will copy the elements from location LIST IN to location LIST OUT. While ignored. if an occurs more than once then the copies and In essence, the subroutine eliminates the replicated elements from LIST IN places the results in LIST OUT. Note that you need to update number m (the first element on the top which is the actual number of elements in LIST OUT after eliminating all replicates.

Answer 1

Program : Find a sum of two integer arrays;
* Input : The input arrays are signed 16-bit integers in arr1 and arr2
* Output : Display sum of arr1 on P1OUT&P2OUT and sum of arr2 on P3OUT&P4OUT
