Abstract: An approach to optimize specular highlight generation is presented. A single microprocessor instruction is used to generate an intensity value based upon a viewing angle value. An application stores a viewing angle value in an input register. When called, the “intensity instruction” retrieves the viewing angle value from the input register, and calculates an intensity value using three distinct steps. In turn, the intensity instruction stores the intensity value in an output register for the application to retrieve and further process. In one embodiment, the invention may be implemented using PowerPC™ assembly and VMX™ or Altivec™ instructions. In this embodiment, the intensity instruction may be represented as a “vspecefp” instruction, which stands for a “vector specular estimate floating point” instruction.

Abstract: A method, computer-readable medium, and an apparatus for implementing a floating point weighted average function. The method includes receiving an input containing 2N input values, 2N weights, and an opcode, where N is a positive integer number and each of the input values corresponds to one of the weights. Furthermore, the method also includes using existing dot product circuit function to generate 2N addends by multiplying each of the input values with the corresponding weight. In addition, the method includes generating a sum value by adding the 2N addends, where the sum value includes an exponent value, and generating the weighted average value based on the sum value by decreasing the exponent value by N. In this fashion, the same circuit area may be used to carry out both dot product and weighted average calculations, leading to greater circuit area savings and performance advantages.

Abstract: The present invention is generally related to integrated circuit devices, and more particularly, to methods, systems and design structures for the field of image processing, and more specifically to vector units for supporting image processing. A dual vector unit implementation is described wherein two vector units are configured receive data from a common register file. The vector units may independently and simultaneously process instructions. Furthermore, the vector units may be adapted to perform scalar operations thereby integrating the vector and scalar processing. The vector units may also be configured to share resources to perform an operation, for example, a cross product operation.
