Subject: [PATCH 00/11] powerpc: Add support for Microwatt soft-core
Date: Tue, 15 Jun 2021 08:56:51 +1000 [thread overview]
Message-ID: <YMfeswgEHeXSLOUF@thinks.paulus.ozlabs.org> (raw)
This series of patches adds support for the Microwatt soft-core.
Microwatt is an open-source 64-bit Power ISA processor written in VHDL
which targets medium-sized FPGAs such as the Xilinx Artix-7 or the
Lattice ECP5. Microwatt currently implements the scalar fixed plus
floating-point subset of Power ISA v3.0B plus the radix MMU, but not
logical partitioning (i.e. it does not have hypervisor mode, the
partition table or nested radix translation).
Paul.
