1. Title: Data Storage Units

2. Introduction: This week in embedded systems, we revisited storage units made from latches and flip flops. These units are used to story memory. Then rom memory was created and simulated with several different data sizes. Then a file was created to read a .coe file.

3. Materials and Methods:
        Materials:
                 - Computer
                 - Vivado Software
                 - GVim Software
        Methods:
             For this homework assignment, simulations for the flips flops were done first. There were several flip flops including: SR flip flop, D flip flop, JK flip flop, and T flip flop. The testbenches were provided for the first two but the last two needed to be written up. Then rom files were made to simulate reading from read-only memory. Several different sized data files were created and simulated. The last task involved reading with the IP blocks.

4. Results:

       Task 1. Repeat the simulations in sections 1-3.

   
             Figure 1. SR Flip Flop files and simulation results.

   
             Figure 2. D Flip Flop triggered by the rising edge.

       Task 2. Write the testbenches and run simulations for section 4 and section 5.

             Figure 4. T Flip Flop files and simulation results. From section 5.

       Task 3. Repeat all the work in section 8 and complete the task described in the end of section 8.

             Figure 8. rom_3bit simulation results.

5. Discussion
    For this week, different latches and flip flops were reviewed and simulated. I rushed through section 8 which had to do with the rom files because I'm almost alwasys behind on my assignments. I did not get to finishing the last task. I loaded the ds_image.coe file into vivado but wasn't sure how to code the module. I wasn't sure what to do with read_en and ce. Plus, like I said, I just ran out of time again.
