MCAPI – lessons learned

Posted by Colin Walls

Colin Walls Some weeks ago, I wrote a blog entry on MCAPI, which seemed to provoke some interest. Last week we ran a Web seminar on this topic, in conjunction with the Multicore Association. This was well attended and seemed well received. You can access the archive recording here. We will be running another session soon, with timing oriented towards European attendees. I have done quite a few Web seminars now … Read More

AMP vs SMP

Posted by Colin Walls

Colin Walls It is becoming common for embedded designs to incorporate more than one CPU - maybe multiple cores on a chip or multiple chips on a board or any combination of these. Indeed, it has been suggested that it will soon be the norm to build systems that way. The use of multiple cores has spawned various technologies and, of course, much terminology and jargon. When new technical terms and acronyms appear, … Read More

ESC Silicon Valley 2010

Posted by Colin Walls

Colin Walls As usual, I attended the Embedded Systems Conference in San Jose, CA last week. I guess it remains the foremost show in the embedded world in North America for sure - probably worldwide. My role was to make some presentations and look after the theater on the Mentor Embedded [our new branding for the Embedded Software Division of Mentor Graphics] booth. I did not have a chance to attend any conference … Read More

Introducing MCAPI

Posted by Colin Walls

Colin Walls I recently wrote about a “multi-core” development project that I worked on many years ago, including some details of how we managed communication between the CPUs. Things have moved on a lot since those days and multi-core is now rapidly becoming the norm in embedded designs. It is, therefore, unsurprising that a degree of standardization is being established. Specifically, the Multicore Association … Read More

Vintage multi-core - the IPC

Posted by Colin Walls

Colin Walls Last week, I wrote about a “multi-core” project that I was working on 30 years ago. To be fair, it was actually “multi-CPU” rather than “multi-core”, but many of the challenges were similar, as was the initial design decision to take the approach of distributing the processing capacity. It is interesting to draw a comparison between the system we were developing all those years ago and modern ideas … Read More

Vintage multi-core - introduction

Posted by Colin Walls

Colin Walls Sometimes I think that there is nothing truly new in the world. With technology, it is often a question of the time being right. On a previous occasion, I looked at programming languages and how what we use nowadays is mostly a development of 30-40 year old technology. It occurred to me that the current enthusiasm for multi-core designs is really nothing new. I browsed some of the literature and titles … Read More

8 bits anyone?

Posted by Colin Walls

Colin Walls It was well over 10 years ago and I was working a trade show booth with a techie colleague. It was quiet and we were bored. We chatted about things that interested us and eventually settled on our common ground: embedded software. He made a reference to “back in the 8 bit days”. I questioned this: “We are in the 8 bit days now!”. He did not believe me … It was not that he thought I was deceiving him … Read More

Multi-core, multi-OS confusion

Posted by Colin Walls

Colin Walls It is increasingly common for embedded designs to be implemented using multiple cores. At Mentor Graphics we are keen to support our customers by providing software and services to help them with such endeavors. We also espouse the idea of using multiple operating systems in such designs. I recently presented a Web seminar on this topic [a recording is available as an archive] and I have written a few … Read More

Multi-core/multi-OS - terminology

Posted by Colin Walls

Colin Walls Working for Mentor Graphics is interesting, but can have some challenges. One of the facets of the company that makes us unique is embedded software. There are a couple of other companies that Mentor would regard as key competitors, but they are both totally focussed on electronic hardware design - “electronic design automation” [EDA]. A very large part of Mentor has that orientation, but we are unique … Read More
