acc1 = -( z10*(x10 - y10) + z11*x11 )
acc2 = -( z20*(x20 - y20) + z21*x21 )
acc3 = -( z30*(x30 - y30) + z31*x31 )
acc4 = -( z40*(x40 - y40) + z41*x41 )
acc5 = -( z50*(x50 - y50) + z51*x51 )
acc6 = -( z60*(x60 - y60) + z61*x61 )
acc7 = -( z70*(x70 - y70) + z71*x71 )
Returns
Returned accumulation vector (8 x int48 lanes)
Parameters
xbuffInput buffer of 32 elements of type int16
xstartStarting position offset applied to all lanes of input from X buffer.
xoffsets4b offset for each lane, applied to both x and y buffers. LSB apply to first lane
ybuffRight input buffer of 32 elements of type int16
ystartStarting position offset applied to all lanes for input from Y buffer.
mtapSelector for partial pre-subtraction relative to xstart
zbuffInput buffer of 8 elements of type int32
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.
