#1: conditional move instruction |
|
|
|
|
|
|
|
|
|
|
|
| ..R1
is address of fluid[i,j] |
|||||||||
| ..R2
is address of U[i,j] |
|||||||||
| ..R3
is address of U[i-1,j] |
|||||||||
| ..F4 is 0.0 |
|||||||||
| LW
R4, (R1) |
|||||||||
| LD
F1, (R3) |
|||||||||
| LD
F2, -1(R2) |
|||||||||
| ADDD
F3, F1, F2 |
|||||||||
| CMOVE
F5, F3, F4, R4 |
|||||||||
| SD
(R2), F5 |
|||||||||
|
|
|
|
|
| if
(fluid[i][j]==0) { |
||||
| U[i][j] = U[i-1,j]+U[i,j-1]; |
||||
| }
else { |
||||
| U[I,j] = 0.0; |
||||
| } |

|
|
| If
R4=0, move F3 to F5, else move |
|
| F4 to F5 |
|
| CMOVE
F5, F3, F4, R4 |
