Un poco de historia del BSC, qué es lo que hacemos, hacia dónde vamos, y las oportunidades para desarrollar su carrera allá.

PARTE 2: Vitruvius+: An Area-Efficient RISC-V Decoupled Vector Coprocessor for Vitruvius+High Performance Computing Applications

The maturity level of RISC-V and the availability of domain-specific instruction set extensions, like vector processing, make RISC-V a good candidate for supporting the integration of specialized hardware in processor cores for the High-Performance Computing (HPC) application domain. In this paper1 , we present Vitruvius+, the vector processing acceleration engine which represents the core of vector instruction execution in the HPC challenge that comes within the EuroHPC initiative. It implements the RISC-V vector extension (RVV) 0.7.1 and can be easily connected to a scalar core using the Open Vector Interface (OVI) standard. Vitruvius+ natively supports long vectors: 256 Double Precision (DP) floating-point elements in a single vector register. It is composed of a set of identical vector pipelines (lanes), each containing a slice of the Vector Register File (VRF) and functional units (one integer, one floating-point). The vector instruction execution scheme is hybrid in-order/out-of-order and is supported by register renaming and arithmetic/memory instruction decoupling. On a standalone synthesis, Vitruvius+ reaches a maximum frequency of 1.4 GHz in typical conditions (TT/0.80V/25°C) using GlobalFoundries 22FDX FD SOI. The silicon implementation has a total area of 1.3 mm2 and maximum estimated power of ∼920 mW for one instance of Vitruvius+ equipped with eight vector lanes.
