Overview

Simple intrinsics for buffer self-multiplication. For more information in lane selection please refer to here.

Functions

v8acc48 mac8 (v8acc48 acc, v8int16 xbuff)
 Self multiplication with accumulate on a single buffer (equivalent to lane by lane power of 2). For more information in lane selection please refer to here.
 
v8acc48 mul8 (v8int16 xbuff)
 Self multiplication on a single buffer (equivalent to lane by lane power of 2). For more information in lane selection please refer to here.
 

Without squares

These intrinsics have a default x/y square of 0x3210.

v8acc48 mac8 (v8acc48 acc, v64int16 xbuff, int xstart, int xoffsets, int xstep, int zstart, int zoffsets, int zstep)
 Self multiplication with accumulate on a single buffer. For more information in lane selection please refer to here.
 
v8acc48 mac8 (v8acc48 acc, v32int16 xbuff0, v32int16 xbuff1, int xstart, int xoffsets, int xstep, int zstart, int zoffsets, int zstep)
 Self multiplication with accumulate combining two buffers into one. For more information in lane selection please refer to here.
 
v8acc48 mul8 (v64int16 xbuff, int xstart, int xoffsets, int xstep, int zstart, int zoffsets, int zstep)
 Self multiplication on a single buffer. For more information in lane selection please refer to here.
