riscv provides a vector unit instead of a traditional simd

  I thought I had read somewhere that the Packed SIMD (P) extension was still going to be developed for implementations that don't need the full-blown Vector (V) extension, for example, embedded processors for digital signal processing. https://github.com/riscv/riscv-p-spec/ https://github.com/riscv/riscv-p-spec/ https://github.com/riscv/riscv-v-spec/ https://github.com/riscv/riscv-v-spec/

    There dosent seem to be a lot of demand for it Debian would target typical linux application usage

    The P extension is quite "small" though - it works in the regular 32/64-bit x1-x31 GPRs, which is also pretty far from traditional SIMD.

    The packed SIMD effort hasn't moved in years, as there's no interest (commercial or otherwise). This is in no small part due to the ratified V extension scaling well in both directions (smaller and larger designs).
