OVI: The Open Vector Interface - Roger Espasa & Alberto Moreno, SemiDynamics

OVI: The Open Vector Interface - Roger Espasa & Alberto Moreno, SemiDynamics OVI is an open protocol to connect a RISC-V core with a loosely coupled vector unit compliant to the RISC-V vector specification. OVI has been used to connect the Avispado core from SemiDynamics to the Vitriuvius vector unit from the Barcelona Supercomputing Center. In this talk we will cover the details of the protocol and explain how it can enable a quicker implementation of a RISC-V compliant vector unit with custom extensions.
