Embecosm has been working with Southampton University as an industrial partner for it’s MEng final year Group Design Projects. The scope of this project was to create a RISC-V based instruction set extension to accelerate AI and machine learning applications. Read More
The global hardware and software community is developing a huge range of RISC-V based solutions. As part of its commitment to that community, Embecosm is making freely available pre-built up-to-date GCC tool chains. This will ensure that software is built with the latest RISC-V compiler features and optimizations. Read More
Introduction One of the currently proposed draft ISA extensions for RISC-V is the Bit Manipulation Instructions extension (from henceonwards referred to as the “Bitmanip” or “BMI” extension.) It proposes to provide fast and direct instructions for commonly-used bitwise operations, often… Read More
Introduction The RISC-V Instruction Set Manual describes the current status of the RISC-V ISA and its extensions. Among these there’s a mention of the ‘B’ extension that is meant to host specific instructions for bit… Read More
What is RI5CY? RI5CY is a 4-stage in-order pipelined RISC-V core written in SystemVerilog. It has become very popular for many applications, including being adopted as the first Core-V core in the OpenHW Group family, as… Read More
The patches that I submitted to add 32-bit RISC-V architecture support to Buildroot have recently been committed upstream. As part of this patchset a configuration was added to enable the Buildroot autobuilders so that any potential build… Read More
Jeremy Bennett and Mark Corbin will be speaking at the BCS Open Source Specialist Group – Machines and Systems of past, present, future event on Thursday 17th January 2019. This event is hosted at The BCS, the Chartered Institute for… Read More
Background I have been working on adding RISC-V 64-bit architecture support to Buildroot. Buildroot is an embedded Linux build system that generates complete system images from source for a wide range of boards and processors. Buildroot uses makefiles… Read More
I recently attended the GNU Tools Cauldron in Manchester, where Roger Espasa from Esperanto Technologies and I ran a BoF session on GCC support for the RISC-V Vector (V) extension. This is an interesting topic, because the V… Read More
Hi, I’m Sam Leonard, and I’m going into my second year of A-levels. I’m at Embecosm for a week as a work experience student, working on producing an exploit as a proof of concept for the Stack Erase feature that… Read More
