Fantastical Creatures

In my day job I work in the High-Level Synthesis group at Siemens EDA, specifically focusing on algorithm acceleration. But on the weekends, sometimes, I take on the role of amateur cryptozoologist. As many of you know, the main Siemens EDA campus sits in the shadow of Mt. Hood and the Cascade Mountain range. This is prime habitat for Sasquatch, also known as “Bigfoot”. This weekend, ar... » read more

High-Level Synthesis Propels Next-Gen AI Accelerators
By Russell Klein - 20 May, 2024 - Comments: 0

Everything around you is getting smarter. Artificial intelligence is not just a data center application but will be deployed in all kinds of embedded systems that we interact with daily. We expect to talk to and gesture at them. We expect them to recognize and understand us. And we expect them to operate with just a little bit of common sense. This intelligence is making these systems not just ... » read more

Fast, Low-Power Inferencing
By Russell Klein - 10 Dec, 2020 - Comments: 1

Power and performance are often thought of as opposing goals, opposite sides of the same coin if you will. A system can be run really fast, but it will burn a lot of power. Ease up on the accelerator and power consumption goes down, but so does performance. Optimizing for both power and performance is challenging. Inferencing algorithms for Convolutional Neural Networks (CNN) are compute int... » read more

Correlating Software Execution With Switching Activity To Save Power In SoC Designs
By Russell Klein - 09 Mar, 2017 - Comments: 0

There is probably no more pointless waste of energy than lighting and heating a room that is empty. The obvious optimization: notice that no one is there and turn off the lights. It works the same on an SoC or embedded system. To save energy, system developers are adding the ability turn off the parts of the system that are not being used. Big energy savings but with no compromise to functional... » read more

Finding The Unexpected In High Performance Designs
By Russell Klein - 09 Feb, 2017 - Comments: 0

It was growing dark as I drove a winding road on Mt. Hood, deep in the American northwest forest. The firs were thick, creating a lot of shadows and making it tough to see things clearly. Then out of the corner of my eye, I swear I saw a 10-foot “man” covered with brown fur. It looked a lot like a Wookie. But everyone knows Wookies aren’t real. It had to be Bigfoot! I slammed on th... » read more

Finding Evasive System-Level Bugs Using Memory Consistency Algorithm
By Russell Klein - 12 Jan, 2017 - Comments: 0

Over Easter weekend in 2015 there was a jewelry heist at the safe deposit building at Hatton Gardens in London. The safe deposit vault was in the basement of a building and is used by jewelers in the area for storing large amounts of diamonds, jewelry, precious metals, and cash. The thieves made off with over $300 million in loot, making it the biggest heist in British history. For a while it l... » read more

Optimizing Emulator Utilization
By Russell Klein - 11 Aug, 2016 - Comments: 0

The growing pressures of market schedules, design complexity and the ever-increasing amount of embedded software in today’s SoCs has put verification in the hot-seat. Now that new emulation tools can link hardware and software verification, SoC designers are turning to emulation more than ever before to debug embedded software. The standard method for debugging software with an emulator is wi... » read more
