Another recent experiment of mine 📢 Introducing #emixa, a Python-Scala library to characterize and visualize the errors produced by #inexact/#approximate #arithmetic units. Now available in open-source: github.com/aproposorg/emixa

GitHub - aproposorg/emixa: Error Modeling of IneXact Arithmetic (EMIXA)

Error Modeling of IneXact Arithmetic (EMIXA). Contribute to aproposorg/emixa development by creating an account on GitHub.

Self-promotion incoming 📢 Are you looking for a flexible library of #inexact/#approximate #arithmetic units for your next #hardware design? Consider using my approx library, now extended with (in-)exact (parallel) accumulators: github.com/aproposorg/approx

#emixa represented a chance for me to try using run-time #reflection in combination with hardware tests in @scala_lang to reduce the developer efforts required to use the library vastly. The #Python front-end handles passing arguments, #Scala transforms them to the proper types💡

For example, defining an automated test of an #inexact OFLOCA #adder is as easy as:
Definition of an automated test of an inexact OFLOCA adder.

Six months have passed since the #Euromicro #DSD conference and the proceedings have finally been published, my paper included 📄 Consider giving it a read at: ieeexplore.ieee.org/document…

Back in Finland after a busy week of travelling. It was a pleasure to catch up with colleagues from my internship at @AMD and learn from the workshops and tutorials at the #FPL2023 conference. Rarely have I experienced an event as well organized!

Disclaimer: the source code for CGRAgen yet has to be made available in open source as I have been preoccupied with other pressing tasks. It is still projected to be published on the #HorizonEU @APROPOS_Project GitHub page once ready 💻

Six of my co-ESRs in the #HorizonEU @APROPOS_Project and I have just wrapped up our collaboration on transforming a project-internal report into a substantial article on adaptive #approximate #computing.

Today marks one year since the official publication of our systematic literature. The article has since been a source of inspiration for my work and received a great deal of interest from other researchers, standing at more than 4000 downloads via ACM's Digital Library alone 🤩

This week, I also took part in the last official event as part of the #HorizonEU #APROPOS_Project hosted by @PoliTOnews. Unlike the prior events that were predominantly filled with lectures by external speakers, this event was full of presentations by the ESRs, myself included.
