Machine Problem 5: Grading Report

Please print this page and provide it to the TA when you demonstrate your machine problem.
The TA should verify each functionality item, initial the 'Demo' box, assign functionality and bonus points,
then copy your files to the HANDIN floppy. This page should be stapled to the front of your printed .ASM program.

General Notes

All procedures should preserve required registers
(C Calls must preserve DS, SS, SI, DI)
(ASM Calls should preserve all registers)
Results should exactly match those for the library-based code.
Use of MASM dot commands (.if .else .while ..) is prohibited.
Points are only awarded for routines that work completely.

Category	Min	Max
ScaleTank Draws a scaled tank into the ScreenBuffer, centered at the location specified by XPos, YPos. Rotation determines the view of the tank. PlayerNum determines which tank is drawn. Works like library case for 'MAIN 1', 'MAIN 2', and 'MAIN 3' Provides smooth, linear scaling betwen all possible scale values (1..99 = reduction, 100=same, >100=increase) -10 for implementation that cannot support ALL fractions Clips boundries of tank when partially (or completely) off screen -10 for implementations that wrap or crash	0	20
Program Execution Speed To receive credit for speed in this section, the student's scaletank must be functional. Students may use LIBMP5 calls for other functions. Compare the code of the first test case ('MAIN 1') to that of the lab manual. Students should not modify any lines of code for this testcase. Run 'MAIN 1' with student's executable. Use the best number of three runs Running Time = ___________ 1/18 s Run 'I:\ECE291\MP5\MAIN 1' with library-based executable: Use the best number of three runs Running Time = ___________ 1/18 s Divide student time by library time. and multiply by 100% Speed Fraction = ___________ % Assign points as follows: Faster than library (less than 71 ticks): +12 (2 point bonus) Just as fast as library (equal to 71 ticks): +10 (full credit) Within 75% of library speed (less than 100 ticks): +8 Within 50% of library speed (less than 142 ticks): +6 Within 25% of library speed (less than 284 ticks): +4 Within 10% of library speed (less than 710 ticks): +2 More than 10 times slower (more than 710 ticks): 0	0	10
HallDemo Moves three tanks in a long hallway. Green tank is moving towards the camera, Illini tank is moving away. A second Illini tank scrolls along the bottom.	0	10
MyDemo Exercises scalable bitmaps, walls, and motions in a student-created animation. Award students for imagination and creativity.	0	10
