Write a MIPS program to add two matrices and store the result in memory starting

Question

Write a MIPS program to add two matrices and store the result in memory starting at address given in s4. The matrices are of the size 2 X 3 each. The two matrices are stored starting at two memory locations whose addresses are given in two registers, s2 and s3. Each number in the matrix is represented in signed 2’s complement form.

Part 2: For two matrices that are stored at starting addresses given by s0 and s1 respectively, with M1 of size 2 X 3 and M2 is of size 3 X 2; perform the multiplication of M1 X M2 and store the result in memory starting at address given in s5. Each number in the matrix is represented in signed 2’s complement form.

Solution :

# `MAT` means
# 1, 2, 3
# 4, 5, 6
# 7, 8, 9
# `mat` means
# 9, 8, 7
# 6, 5, 4
# 3, 2, 1
