Apparatuses and methods for processing single instruction for image transformation from non-integral locations

A method for non-integral transformation of an image, comprising:

• receiving a single instruction containing a memory address of an input image, a second memory address of an output image, an array of offsets associated with the output image, and an interpolation type parameter;
• fetching a plurality of pixels of the input image from memory based on the memory address of the input image;
• determining weights to be applied to the plurality of pixels of the input image based on an element of the array of offsets and the interpolation type parameter;
• calculating an output pixel of a transformed image by multiplying the plurality of pixels of the input image by the weights and summing each resulting product;
• and
• writing the output pixel of the transformed image to the second memory address.

A non-transitory computer-readable storage medium comprising instructions executable by a processor, which when executed by the processor causes the processor to perform an image transformation utilizing a single instruction multiple data (SIMD) operation, the non-transitory computer-readable storage medium, comprising:

• a SIMD instruction which specifies:
• a memory address of an input image;
• a second memory address of an output image;
• an array of offsets associated with the output image;
• an interpolation type parameter;
• and
• code for fetching a plurality of pixels of the input image based on the memory address of the input image;
• code for determining weights to be applied to the plurality of pixels of the input image based on an element of the array of offsets and the interpolation type parameter;
• code for calculating an output pixel of a transformed image by multiplying the plurality of pixels of the input image by the weights and summing each resulting product;
• and
• code for writing the output pixel of the transformed image to the second memory address.
