The LibreSOC Project: Simple-V Vectorisation
summary
Explains why LibreSOC created a new vector extension (Simple-V) for OpenPOWER to reduce hardware, driver and integration complexity for embedded/mobile systems. Compares traditional SIMD and software-only vector designs (Larrabee/Nyuzi) with Cray-style variable-length vectors and notes inefficiencies in SIMD (example: a 250-instruction POWER9 VSX strncpy vs ~14 with Cray vector principles). Describes Simple-V’s background, concepts, and plans to formalize it as an OpenPOWER extension (supported by an NLnet grant).
