It's the Second Mouse That Gets the Cheese

By Paul McLellan | 20 May 2020

I love short phrases that make you think, "Wait...what?" and then you think about it and gradually realize it is true. A good example is the title of today's blog post: "It's the second mouse that gets the cheese". Product...

A History of Neural Networks

By Paul McLellan | 19 May 2020

Research on biological neurons started back in the 1940s, before computers, and long before integrated circuits. Some research started at IBM in the 1950s to model neurons and, in 1956, the Dartmouth Summer Research Project on Artificial Intelligenc...

Tensilica HiFi DSPs with Dolby Atmos for Soundbars

By Paul McLellan | 15 May 2020

Do you know what a soundbar is? Years ago, if you wanted to build a good home theater then you'd need a TV projector (or a projection TV) costing over $10,000, and a set of expensive speakers to go with your Dolby 5.1 ("five point one&...

By Paul McLellan | 12 May 2020

Today is the 200th anniversary of the birth of the first woman member of the Royal Statistical Society (in London, the title is unqualified since there were no other statistical societies). I've written a bit about her before in my post The Lady...

Why Create an SoC?

By Paul McLellan | 11 May 2020

I've been in the semiconductor and EDA industries for nearly forty years. One thing I've noticed that hasn't changed is that we love our chips and the tools to design them. Designing a chip that is a perfect match to a unique purpose is ...

Hearables and Earbuds

By Paul McLellan | 8 May 2020

Do you have a set of Bluetooth earbuds yet? If not, you will. The iPhone was the first to kill the ubiquitous 3.5mm headphone jack, but many other manufacturers have quietly followed. Of course, various wired adapters are available, but the replacem...

Signoff in the Cloud

By Paul McLellan | 4 May 2020

Here's a nightmare. You sign off your design with the usual margins. It is a 7nm chip that is meant to run at 3GHz. But it only runs at 2.7GHz. You get Cadence to help you work out what is going on. It turns out that it is due to a critical path...

I'm not a big fan of the J-school approach to writing an article where you start with some anecdote that has nothing to do with what you are going to write about. Most articles like that are best started on the second page. But I did l...
