• Write an ARM assembly code to calculate the product of two matrices. Each element should be 4 byte (32 bit) integer. Let’s assume that the number of columns of the first matrix is equal to the number of rows of the second matrix. The number of rows of the first matrix is stored in R0 register. The number of columns of the first matrix (the number of rows of the second matrix) is stored in R1 register. The number of columns of the second matrix is stored in R2 register. The code as a whole should work correctly. For an example case, follow/trace the code and show that it works correctly. • Write detailed technical explanations for each line of your code as your unique comments. Comments should be descriptive. There should be no similarity to other students or to other resources.
• Analyze your assembly code according to the 5-Stage Pipeline ARM Organization. Identify the problems that will arise in terms of pipelining; pipeline hazards. You can use table form to track 5 stages. Do not offer solutions for now.
• Optimize your assembly code to minimize pipeline hazards. Explain how these changes will work.
• What are the benefits of using cache for this problem? Please explain in detail.
