Color Operation Definitions
Define a multiplication, addition, comparison, ROP of a Color value (R,G,B,A) each as one operation
- Will count an equation of the form f*C+(1-f)*C as 3 ops, but only 1 pipeline stage
- 2 mults, 1 add, 1 pipeline stage
- (1-f) is not counted, in fixed point this is one’s complement
- We combine multiply-add as one clock
- Assume R,G,B,A values computed in parallel.
- An alpha-only comparison still counts as one op.
