" summary

SiFive offers Linux-capable vector CPUs with concrete specs: P270 256-bit targets smallest-area multi-core in-order designs, while X280 512-bit with SiFive Intelligence extensions adds custom AI/ML opcodes, a vector coprocessor interface, up to 16-core scaling, and willguard security. Measured results show 24x (vector) and 6x (extensions) on MobileNet v1 versus a scalar core. Tooling includes SIMDe-to-RISC‑V conversion, LLVM auto-vectorization, and TensorFlow Lite optimizations already ported to the X280.
