quadrilatero is a Systolic Array co-processor based on a custom set extensions available here
derived from a subset of the RISC-V RVM ISA extensions proposed by T-HEAD Matrix.
It has been developed at the Embedded System Laboratory (ESL) at EPFL.
It uses the CORE-V-X-IF interface to interface with the OpenHW Group CPUs and the OBI protocol to interface with memories.
An LLVM extended with the proposed instructions is available here
