  • Parameter 'zstart' must be a compile time constant.

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

acc0 = -( z00*x00 )
acc1 = -( z10*x10 )
acc2 = -( z20*x20 )
acc3 = -( z30*x30 )
acc4 = -( z40*x40 )
acc5 = -( z50*x50 )
acc6 = -( z60*x60 )
acc7 = -( z70*x70 )
Returns
Returned accumulation vector (8 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
xyconjSelector for conjugation in X and Y buffers
zbuffInput buffer of 8 elements of type cint16
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
