Report write-up: 1. Not a complete technical document. Should have Background and Introduction (including system behavior requirement), Method: Analysis and Design, Realization, Results and Discussions (including CPU load and timing analysis), and Conclusion, followed by citations and appendices as appropriate. 2. Not sufficient details on hardware description. It should at least cover the lab manual’s and instructor's explanation plus something extra you find (from the internet). Describe with a hierarchy, from high level overview to low level details. 3. Not sufficient details in code explanation. Everything in the picture (code) should be explained. Describe with a hierarchy, from high level overview to low level details. 4. Some figures have poor quality. 5. Graphs of the collected data can be improved. 6. Every figure should be referred by the text. 7. Provide references. At least the lab manual should be cited. 8. If you have questions regarding technical writing, consult and follow MLA (Modern Language Association) style from the book “ MLA Handbook for Writers of Research Papers or internet resources. Technical contents: 1. Incorrect hardware explanation. 2. Incorrect code explanation. 3. Insufficient or incorrect real time software analysis based on the timing diagram and finished late counts. These could be thread labels marked wrong, CPU loading percentage substantially off because you did not zoom out sufficiently to get representative statistics, or not checking the finish late counts on time critical threads. 4. Insufficient, inconsistent, or incorrect proof of the system based on the graphed data or discussion. Other comments: Grade: 8 out of 10
