| Sumario: | RISC-V continues to grow in popularity both in academia and industry. Recently, version 1.0 of the vector extension was ratified for public use and sparked renewed interest in vector processing. This is especially true in domains like High-Performance Computing (HPC) where the benefits of vectors can be fully exploited. This Master Thesis shows the integration of the Vitruvius Vector Processing Unit (VPU) with the Lagarto Ka, a dual-issue out-of-order RISC-V processor, through the Open Vector Interface (OVI). It describes the changes that have been made in the core to support the execution of vector instructions. The design has been tested, evaluated and compared to DVINO, a chip with earlier generations of the core and VPU. Lagarto Ka plus Vitruvius achieves up to 10 times more performance in vector instructions compared to its predecessor. It also reached a frequency of 1.5GHz when synthesized in 7nm. |
