uct_shift	int	Upshift value to the four upshifted lanes
zbuff	v16int16	Input buffer of 16 elements of type int16
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.

Parameters

Input/Output	Type	Comments
return	v16acc48	Returned accumulation vector (16 x int48 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. xstart is restricted to multiples of 2 as granularity for xbuff is 32-bit.
xoffsets	unsigned int	4b offset for each lane, while each second lane is an offset to the lane before + 1, applied to both x and y buffers. LSB apply to first lane
xstep	unsigned int	Step between each column for selection in the x and y buffers. Ystep is symmetric to xstep (ystep advances by -xstep). xstep is restricted to multiples of 2 as granularity for xbuff is 32-bit.
xsquare	unsigned int	Select order of the mini-permute square (default=0x3210). LSB apply to first element
ybuff	v32int16	Right input buffer of 32 elements of type int16
ystart	int	Starting position offset applied to all lanes for input from Y buffer. ystart is restricted to multiples of 2 as granularity for ybuff is 32-bit.
ysquare	unsigned int	Select order of the mini-permute square (default=0x3210). LSB apply to first element
uct_col	int	Select which column of data from the Y buffer to upshift for the lower half of the output accumulator. This must be a compile time constant.
uct_shift	int	Upshift value to the four upshifted lanes
zbuff	v16int16	Input buffer of 16 elements of type int16
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.

Note

• This intrinsic uses the 'square' parameter, to have more information on how to use this please go here
• For more information on how data selection works from the buffers go here. For this intrinsic, the data buffer uses the 16bx16b scheme and the coefficient buffer uses the general scheme.
• Parameter 'zstart' must be a compile time constant.
