Hitachi Intrinsic Functions

The following table shows Hitachi intrinsic functions with a description of the purpose of each.

Programming element Description
_Convolve Computes the summation of two vectors.
_Dot3dVW0 Computes the inner product of a pair of three or four-dimensional vectors with the "w" coordinate forced to 0.
_Dot3dVW1 Computes the inner product of a pair of three or four-dimensional vectors with the "w" coordinate forced to 1.
_Dot4dV Computes the inner product of a pair of four-dimensional vectors.
__fmac Multiplies two float values and add to a third float value.
_LoadMatrix Loads a 4x4 matrix into the extended floating-point register bank.
__movca Move with cache block allocation.
