* Unsafe configurations *
|
|
*----------------------------------------------------------------------------*
|
|
* Following macro switches are used to improve performance with aggressive *
|
|
* methods which might cause errors or distortions in some cases. *
|
|
* Those macros are undefined by defaults. Please use with cautions. *
|
|
*----------------------------------------------------------------------------*
|
|
* *
|
|
* 1. __ARM_2D_CFG_UNSAFE_IGNORE_CALIB_IN_TRANSFORM__ *
|
|
* This option is used to remove calibration in angle computations to gain *
|
|
* a better performance, small error might be noticible for angles like *
|
|
* 90, 180, 270 etc. *
|
|
* *
|
|
* 2. __ARM_2D_CFG_UNSAFE_NO_SATURATION_IN_FIXED_POINT__ *
|
|
* This option is used to speed up M-cores without DSP support *
|
|
* It skips saturation in the QADD/QDADD/QDSUB involved in the rotation. *
|
|
* The chances of overflow remain low as elements involved are using *
|
|
* non-accumulating Q15.16 format and integer parts are in the range of *
|
|
* the screen size providing enough margin. *
|
|
* *
|
|
* 3. __ARM_2D_CFG_UNSAFE_IGNORE_ALPHA_255_COMPENSATION__ *
|
|
* When define this macro, alpha value 0xFF will not be treated as opaque *
|
|
* in mask related operations you can barely see the background. Defining *
|
|
* this macro can get a big performance uplift. *
