When I posted earlier on Qualcomm presenting with ANSYS on differential energy analysis, I assumed this was just the usual story on RTL power estimation being more accurate for relative estimation between different implementations. I sold them short. This turned out to be a much more interesting methodology for optimizing total… Read More
Just when you thought you knew all the possible foundations for computing, along comes another one. Forget von Neumann, this approach models Ising machines, systems built on solving a statistical ensemble model of ferromagnetism. The concept is quite simple. Imagine a lattice of magnetic dipoles/spins, each of which can only… Read More
We periodically see that “software ate the world” line – I’m pretty sure I’ve used it a couple times myself. The fact is, software doesn’t run itself; never has, never will. Somewhere there has to be an underlying computer. First it was on beads, then in gears, then in tubes.… Read More
Popular companies designing smart phones, CPUs, GPUs and Memory components all employ teams of custom IC designers to create the highest performance chips that are as small as possible, and at the lowest costs. How do they go about doing custom IC design migration and optimization when moving from one process node to another one?… Read More
What happens when you get a panel of four executives together with an industry-leading journalist to discuss tradeoffs in IoT designs? After the obligatory introductions, Ed Sperling took this group into questions on power, performance, and integration.… Read More
Several companies have attacked the QoS problem in SoC design, and what is emerging from that conversation is the best approach may be several approaches combined in a hybrid QoS solution. At the recent Linley Group Mobile Conference, NetSpeed Systems outlined just such a solution with an unexpected plot twist in synthesis.
The… Read More
There are two camps of thinking on the IoT: those who believe Bluetooth and Wi-Fi rule the edge, and those who support any of dozens of other wireless networking specifications for their various technical advantages. The ubiquity of Wi-Fi in homes helps devices connect in a few clicks – so why don’t more IoT designers use it?… Read More
We’ve been saying for a while that it looks like there is a resurgence in design starts for ASICs targeting the IoT. A recent webinar featuring speakers from ARM and Open Silicon (and moderated by Daniel Nenni) affirms this trend, and provides some insight on how these designs may differ from typical microcontrollers.
One of my first… Read More
In our previous post on SoC memory resource planning, we shared 4 goals for a solution: optimize utilization and QoS, balance traffic across consumers and channels, eliminate performance loss from ordering dependencies, and analyze and understand tradeoffs. Let’s look at details on how Sonics is achieving this.… Read More
The classical problem every MBA student studies is manufacturing resource planning (MRP II). It quickly illustrates that at the system level, good throughput is not necessarily the result of combining fast individual tasks when shared bottlenecks and order dependency are involved. Modern SoC architecture, particularly … Read More
