Running Multiple Operating Systems: Hypervisors

Running Multiple Operating Systems: Hypervisors
by Paul McLellan on 11-08-2013 at 9:19 am

How do you run multiple operating systems on the same processor? You use virtualization and you run a hypervisor underneath all the so-called “guest” operating systems. So what is virtualization?


Virtualization started with VM/370 developed in 1972 at IBM (the current version is still in use). Here is how it works.… Read More

Xilinx and TSMC: Volume Production of 3D Parts
by Paul McLellan on 11-07-2013 at 1:23 pm

A couple of weeks ago, Xilinx and TSMC announced the production release of the Virtex-7 HT family, the industry’s first heterogeneous 3D ICs in production. With this milestone, all Xilinx 28nm 3D IC families are now in volume production. These 28nm devices were developed on TSMC’s Chip-on-Wafer-on-Substrate (CoWoS)… Read More


Dassault Patent on Hierarchy Management

Dassault Patent on Hierarchy Management
by Paul McLellan on 11-05-2013 at 5:05 pm

Dassault have recently been granted a patent on their approach to managing design hierarchy. I asked them how long it took from filing the patent until it was granted and they said the whole process had taken 8 years. It is a bit of an indictment of the patent system when it takes 8 years, also known as 4 or 5 process nodes, for a patent to… Read More

nVidia: Virtual Platform/Emulation Hybrid
by Paul McLellan on 11-05-2013 at 11:57 am

I was the VP marketing at VaST Systems Technology and then at Virtutech. Both companies sold virtual platform technology which consisted of two parts:

  • an extremely fast processor emulation technology that actually worked by doing a binary translation of the target binary code (e.g. an ARM) into the native instruction set of the

Synopsys Creates a High-performance ARC Core

Synopsys Creates a High-performance ARC Core
by Paul McLellan on 11-05-2013 at 10:00 am

ARC is a family of configurable processors. Originally it was a standalone company in the UK (what is it with the UK and processor cores?) spun out from Argonaut Software. The A in ARC stood for Argonaut originally. ARC International was acquired by Virage and then Virage was acquired by Synopsys so now it is part of Synopsys Designware… Read More

Addressing Power at Architectural and RTL Levels

Addressing Power at Architectural and RTL Levels
by Paul McLellan on 11-03-2013 at 4:30 pm

Major power reductions are possible by reducing power at the RTL and system levels, and not just at the gate and physical level. In fact, as is so often the case in design, changes can have much more impact when done at the higher level, even given that at that point in the design there is less accurate feedback about changes. Later the… Read More
