Those are interesting side-notes, but for things like adding 32-bit multiplier HW into 8051, if that counts, then we're pretty close to modern x86 counting since it evolved out of 8088 / 8086, but now has 512-bit wide SIMD-integer stuff like vpmaddwd zmm0, zmm0 / vpaddd zmm1, zmm0 to do 32x 16-bit multiply-accumulate operations in parallel, with a throughput of 1 cycle on Skylake-X / Ice Lake (and room to load to get sum-of-squares of an array.) | |
