Complex multiply-negate intrinsic function with dynamic x buffer conjugation using small X input buffer.

acc0 = -( z00*x00 + z01*x01 + z02*x02 + z03*x03 )
acc1 = -( z10*x10 + z11*x11 + z12*x12 + z13*x13 )

acc3 = -( z30*x30 + z31*x31 + z32*x32 + z33*x33 )
Returns
Returned accumulation vector (4 x cint48 lanes)
Parameters
xbuffInput buffer of 16 elements of type cint16
xstartStarting position offset applied to all lanes of input from X buffer.
xoffsets4b offset for each lane, applied to the x buffer. LSB apply to first lane
xstepStep between each column for selection in the xbuffer.
xyconjSelector for conjugation in X and Y buffers
zbuffInput buffer of 16 elements of type int16
zstartStarting position offset applied to all lanes for input from Z buffer. This must be a compile time constant. Only the 4 LSB of the argument are used.
zoffsets4b offset for each lane, applied to input from Z buffer. LSB apply to first lane
zstepStep between each column for selection in the zbuffer.
Note
  • For more information on how data selection works from the buffers go here. The data buffer and coefficient buffer in this intrinsic use the general scheme.
  • Parameter 'zstart' must be a compile time constant.
