A dual mode device and method is provided for generating cross product or dot
product
from a pair of vectors. The dual mode device generates a cross product or a dot
product from a first vector and a second vector. The first vector has a first set
of components and the second vector has a second set of components. The device
includes a dual mode controller and a dual mode unit. The dual mode controller
receives the first and second vectors and is configured to select vector components
for evaluating a cross product component or a dot product in response to a first
signal. The first signal indicates whether to generate a cross product component
or a dot product. The dual mode unit is coupled to receive the selected vector
components and generates the cross product component or the dot product in response
to the first signal.
