What Is A System Now? - Semiconductor Engineering - Ann Steffora Mutschler

In a recent article in Semiconductor Engineering, Ann Steffora Mutschler states that as designs become part of connected networks, so do the requirements for what’s needed to make it work properly.

Defining a system used to be relatively straightforward. But as systems move onto chips, and as those chips increasingly are connected with applications and security spanning multiple devices, the definition is changing.

This increases the complexity of the design process itself, and it raises questions about how chips and software will be designed and defined in the age of the Internet of Things/Everything. For example, will engineers be developing software-defined hardware, network-defined software and hardware, or application-driven connected systems?

Simon Davidmann, CEO of Imperas, asserts that the classical definition of an electronic ‘system’ still stands—a product composed of both hardware and software components. “But what constitutes a typical ‘system’ has evolved considerably, especially software content, so the technologies and methodologies that are used to develop, debug and test the system become critically important.”

Fast Processor Models of ARM Cores Released by Imperas with Changes to OVP ARM Core Model Licensing Terms

Imperas Open Virtual Platforms Accelerate Embedded Software Development for Multi-Core ARM-based Designs

Oxford, United Kingdom, June 8th 2015 - Imperas™ today announces the release of Open Virtual Platforms™ (OVP™) Fast Processor Models for popular ARM® cores: Cortex®-A17, Cortex®-M0, Cortex®-M0+, and Cortex®-M1. Also announced are changes to the terms of licensing of the OVP ARM Models.

New Extendable Platform Kits™ (EPKs™) of ARM-based devices are available from Imperas, working together with the M*SDK™ tools, to help accelerate embedded software development, debug and test.  EPKs are virtual platforms (simulation models), including processor models plus peripheral models necessary to boot an operating system (OS) or run bare metal applications.  The platform and peripheral models included in the EPKs are open source, so that users can easily add new models to the platform as well as modify the existing peripheral models.  The example OS and/or applications are also included.

OS bring up using virtual platforms - Imagination Blogs - Larry Lapides

Larry Lapides of Imperas recently posted a guest blog at the Imagination MIPS processor blog site. it discusses topics related to Operating System bring up and how virtual platform and advanced tools can provide signiificant benefits.

Linux has become the general purpose operating system of choice for embedded systems, and is almost always supported for high end SoCs developed by semiconductor vendors.  These SoCs now have multicore processors, and run symmetric multiprocessor (SMP) Linux. Most vendors start with the MIPS Linux distribution, then customize it for the specific SoC (requiring device tree changes), including the necessary drivers for the peripherals on the SoC as well as supporting other customizations and unique features. While the MIPS Linux distribution is a great starting point, that does not make customization and bring up an easy task.

To put it another way:  Just because you get to the Linux prompt doesn’t mean everything is working.

Just where do virtual platforms fit in this?

FlexTiles Adaptive Multicore SoC Virtual Platform Now Available from Imperas

Imperas Technologies Used for FlexTiles Program

Oxford, United Kingdom, 2 June 2015 - Imperas Software Ltd. (www.imperas.com), the leader in high-performance software simulation, today announced that a virtual platform for the FlexTiles platform is now available, based on Imperas™ and Open Virtual Platforms™ (OVP™) simulators and models. 

The FlexTiles platform is a self-adaptive heterogeneous multicore 3D System-on-Chip (SoC) architecture developed by a consortium of universities, research institutes and commercial companies, with funding from the European Union under the Seventh Framework Programme. A major challenge in computing is to leverage multicore technology to develop energy-efficient high-performance systems. This is critical for embedded systems with a very limited energy budget, as well as for supercomputers in terms of sustainability. Moreover, the efficient programming of multicore architectures is critical, especially with more than a thousand cores per SoC predicted by 2020.  These challenges were the drivers for the FlexTiles project.

Capturing Performance - Semiconductor Engineering - Ann Steffora Mutschler

In a recent article in Semiconductor Engineering, Ann Steffora Mutschler explores examples of architectural strategies for getting the best performance out of a power budget.

Virtual platform developer Imperas Software's  tools are being used for power estimation, to enable dynamic analysis of the impact of the complete software stack - OS, firmware, applications - on the power consumption of SoCs and systems, according to CEO Simon Davidmann. "We have seen various architectures used by our customers with power constraints.  What most of these architectures have in common is heterogeneity:  using the right processor for the appropriate task."

He sees the next step in this progression of system architectures as enabling optimized sharing of...

Imperas active with prpl Foundation at IMG Silicon Valley Summit

At the Imagination Technologies Silicon Valley Summit in May 2015 there was a series of presentation and discussions regarding Virtualization, Security and the prpl Foundation.

Imperas is a founding member of the prpl Foundation Security PEG (prpl Engineering Group) and is working to provide solutions to assist electronic product developers to remove risks associated with embedded software development.

Several videos were recorded regarding prpl at the IMG summit - these can be viewed on the prpl youtube channel here.

The Hardware Vanishing Point: Someday, Will it All be Software? - Electronic Engineering Journal - Kevin Morris

"The disciplines of hardware and software engineering have always been intertwined and symbiotic - like the yin and yang of some bizarre abstract beast. Software cannot exist without hardware to execute it, of course, and most hardware today is designed in the service of software. The vast majority of systems being designed today involve a mix of both elements working together, with software steadily inheriting more and more of the complexity load.

Let’s think about that for a minute..."

Problems Ahead For EDA - Semiconductor Engineering - Brian Bailey

At the DVCon conference in Santa Clara in April, Brian Bailey of Semiconductor Engineering hosted a round table discussion on the state of EDA and the opportunities for new startups to grow and succeed.  Imperas CEO and OVP founder, Simon Davidmann was part of the discussion.

EDA Startup Panelists

Other participants were Bill Neifert, chief technology officer at Carbon Design Systems; Randy Smith, vice president of marketing for Sonics; and Michel Courtoy, vice president of marketing and business development for Kilopass Technology.

The discussion is being reported in 3 posts by Brian. There are links to them below.
