Abstract
A data path for a SIMD-based microprocessor is used to perform different simultaneous filter sub-operations in parallel data lanes of the SIMD-based microprocessor. Filter operations for sub-pixel interpolation are performed simultaneously on separate lanes of the SIMD processor's data path. Using a dedicated internal data path, precision higher than the native precision of the SIMD unit may be achieved. Through the data path according to this invention, a single instruction may be used to generate the value of two adjacent sub-pixels located diagonally with respect to integer pixel positions.
