acc1 = cnj(z10)*x10 + cnj(z11)*x11
acc2 = cnj(z20)*x20 + cnj(z21)*x21
acc3 = cnj(z30)*x30 + cnj(z31)*x31
acc4 = cnj(z40)*x40 + cnj(z41)*x41
acc5 = cnj(z50)*x50 + cnj(z51)*x51
acc6 = cnj(z60)*x60 + cnj(z61)*x61
acc7 = cnj(z70)*x70 + cnj(z71)*x71

Parameters

Input/Output	Type	Comments
return	v8cacc48	Returned accumulation vector (8 x cint48 lanes)
xbuff	v32int16	Input buffer of 32 elements of type int16
xstart	int	Starting position offset applied to all lanes of input from X buffer.
xoffsets	unsigned int	4b offset for each lane, applied to the x buffer. LSB apply to first lane
xstep	unsigned int	Step between each column for selection in the xbuffer.
zbuff	v8cint16	Input buffer of 8 elements of type cint16
zstart	int	Starting 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.
zoffsets	unsigned int	4b offset for each lane, applied to input from Z buffer. LSB apply to first lane
zstep	int	Step between each column for selection in the zbuffer.

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