The objective was to direct a main character, named "Doodle", who moves continuously to the right. Players can make it jump over the obstacles along the way by doing the math problems. The players need to calulate and compare the sun of two numbers with the given result.
Our game make use of the following ALU functions, including three functions added by ourselves.
| ALUFN | Operation | Type | Description |
|---|---|---|---|
| 000000 | ADD | ARITH | A + B |
| 000001 | SUB | ARITH | A - B |
| 000010 | MUL | ARITH | A * B |
| 011000 | AND | BOOL | bitwise A and B |
| 011110 | OR | BOOL | bitwise A or B |
| 010110 | XOR | BOOL | bitwise A xor B |
| 100000 | SHL | SHIFT | shift A leftwards by B bits |
| 100001 | SHR | SHIFT | shift A rightwards by B bits |
| 110011 | CMPEQ | CMP | compare if A == B |
| 110101 | CMPLT | CMP | compare if A < B |
| 110111 | CMPLE | CMP | compare if A <= B |
| 111011 | CMPNE | CMP | compare if A != B |
| 111101 | CMPGE | CMP | compare if A >= B |
| 111111 | CMPGT | CMP | compare if A > B |
