things to try:
|
|
|
|

|
|
|
* skip add on the top-byte multiply in sqr8/mul8
|
|
|
|
|
* should save a few cycles, suggestion by jamey
|
|
|
|
|
|
|
|
|
|
* perform the zx += zx^s + cx in 32-bit space, before rounding
|
|
|
|
|
* should improve precision on max zoom, might cost a few cycles
|
|
|
|
|

|
|
|
* patch the entire expanded-ram imul8xe on top of imul8 to avoid the 3-cycle thunk penalty :D
|
|
|
|
|
|
|
|
|
|
* try 3.13 fixed point instead of 4.12 for more precision
|
|
|
|
|
* can we get away without the extra bit?
|
|
|
|
|
|
|
|
|
|
* y-axis mirror optimization
|
|
|
|
|
|
|
|
|
|
* 'wide pixels' 2x and 4x for a fuller initial image in the tiered rendering
|

|
|
|
* maybe redo tiering to just 4x4, 2x2, 1x1?
