Abstract
A texture unit may be used to perform general purpose mathematical computations such as dot products. This enables some general purpose computations and operations to be offloaded from a central processing unit to the texture unit. The texture unit may use linear interpolators in order to perform the dot product calculations.
Claims25
A method comprising:
- using a programmable linear interpolator in a texture unit to calculate a dot product.
An apparatus comprising:
- a processing entity;
- a memory coupled to said processing entity;
- and
- a programmable linear interpolator coupled to said processing entity to calculate a dot product.
1 more element
A computer readable medium storing instructions to enable a computer to:
- determine that a dot product coefficient determined by a texture unit is negative;
- and
- change the sign of the coefficient to a positive value.
