LLVM support for the draft Bit Manipulation Extension for RISC-V
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 manipulation operations. A well known proposal for such extension comes from Claire Wolf and can be found here. We implemented an […]

A FaceNet-Style Approach to Facial Recognition on the Google Coral Development Board
Introduction In this blog post we give an introduction to the topic of facial recognition and describe our approach to the problem introduced in the previous blog post. When deciding to implement facial recognition, FaceNet was the first thing that came to mind. FaceNet is a face recognition pipeline that learns mapping from faces to […]

A dive into RI5CY core internals
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 well as being proposed as the reference for EmBench, a benchmark for embedded processors initiated by David Patterson and […]

Measuring the Accuracy of the Church Clock and Pendulum
The Project For my work experience with Embecosm, I was given a real-life project by Rev. Peter Salisbury, the vicar of St Thomas’ church in Lymington. The project was to measure the accuracy of the church clock and pendulum, by using a magnetic hall effect sensor to detect a magnet stuck to the bottom of […]

Buildroot Support for 32-bit RISC-V
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 issues could be highlighted as part of the Buildroot continuous build process. The system configuration at this stage […]
