Predication is provided so that parallel if/then/else constructs can be performed: critical given that sequential if/then statements and branches simply do not translate successfully to Vector workloads. VSELECT and VINSERT are possible. VSPLAT capability is also provided, which is approximately 20% of all GPU workload operations. Also covered, with elwidth overriding, is the smaller arithmetic operations that caused ISAs developed from the late 80s onwards to get themselves into a tiz when adding "Multimedia" acceleration aka "SIMD" instructions. Experienced Vector ISA readers will however have noted that VCOMPRESS and VEXPAND are missing, as is Vector "reduce" (mapreduce) capability. Compress and Expand are covered by Twin Predication, and yet to also be covered is fail-on-first, CR-based result predication, and Subvectors and Swizzle. -- 2.30.2
