My PhD thesis is titled The Design of a Network Filing System. Yes, that was a research topic back then (and yes, we did call them filing systems not file-systems). One big chapter was on access controls. There are several problems with designing an access control system:
- it needs to be possible to implement it efficiently
- it needs

Debate rages about which approach is better for SoC design: simulation, or emulation. Simulation proponents point to software saving the need for expensive hardware platforms. Emulation supporters stake their claims on accuracy and the incorporation of real-time I/O. A few years back, some creative types coined the term SEmulation,… Read More
Often substrate noise analysis takes place when everything is there on the chip, but that stage comes near the tape-out which is too late to make major changes in architecture, placement, introducing noise protection circuitry for the victims and so on. It was okay when there used to be very little analog content on the chip. But … Read More
Multiple processor cores are now a given in SoCs. Grabbing IP blocks and laying them in a multicore design may be the easy part. While verification is extremely important, it is only the start – obtaining real-world performance depends on the combination of multicore hardware and actual application software. What should engineers… Read More
On the face of it, if we consider a simple ‘diff’ utility, it doesn’t need any explanation; almost everyone in our community would have used it. But imagine the CTO of a company investing his time in explaining how beneficial a specialized ‘Cdiff’ function can be in evaluating IP. Today’s SoC design world can’t live without IP and … Read More
Wireless technology is all around as I use cellular on an Android phone, WiFi to connect my MacBook Pro to the internet, Bluetooth for a headset, ANT+ for my cycling computer, and NFC to speed up electronic payments on the Android phone. Here’s a big picture look at some of the modern wireless standards available to choose from:… Read More
Today, Smartphones and mobile devices have become center of innovation with multiple functions getting into them. Considering the audio or voice application, there can be multi-way conferencing, video chat, complete audio/video streaming, gaming, voice triggering and recognition,… you name an application, and it will … Read More
If you think that the sound atmosphere created by Dolby or Surround–sound audio is the best you can achieve today by using complexes algorithms on DSP, like I thought before knowing about “Object-Based Audio”, you must read these lines! In fact Surround-sound Audio is limited by the number of speakers installed in a room, or a car,… Read More
I visited AtrentaNoida in August 2013 during the inauguration of its newly expanded facility. At that time, I had written about the beautiful environment Atrenta has, with its presence at many sites across the world in my blog – “Innovation + Thoughtful Management = Productive Expansion”. Innovation cannot happen without happy… Read More
This is the 20[SUP]th[/SUP] year of DesignCon and I’m really looking forward to it. While I haven’t attended all 20 I certainly have attended the majority of them. Now it is like a college reunion for me seeing all sorts of friends and former coworkers. One of them is even a keynote but more on that later. This year there are 14 conference… Read More
