Optimizing For Energy In Physical Design


Energy is a precious resource, which should not be wasted. Energy drives economies and sustains societies. Predictions show that the energy of electronics may soon consume 20% to 33% of the global energy supply, as it is highlighted in this blog post about "Design and Manufacturing in 2030" from Greg Yeric, fellow at Arm. Energy efficiency is such an important global issue that it is ... » read more

Is DVFS Worth The Effort?


Almost all designs have become power-aware and are being forced to consider every power saving technique, but not all of them are yielding the expected results. Moreover, they can add significant complexity into designs, increasing the time it takes to get to tapeout and boosting up the cost. Dynamic voltage and frequency scaling (DVFS) is one such power and energy saving technique now being... » read more

Compiling And Optimizing Neural Nets


Edge inference engines often run a slimmed-down real-time engine that interprets a neural-network model, invoking kernels as it goes. But higher performance can be achieved by pre-compiling the model and running it directly, with no interpretation — as long as the use case permits it. At compile time, optimizations are possible that wouldn’t be available if interpreting. By quantizing au... » read more

Blog Review: Sept. 9


Mentor's Jacob Wiltgen considers the recent advances in safety critical engineering and how automated the lifecycle can become, where tools form a set of checks and balances to ensure the accuracy of results. Cadence's Paul McLellan finds out what's new at TSMC, including a new R&D center, fab construction, capacity increases for existing nodes, and what the company sees for beyond its N... » read more

A Performance Analysis Of The First Generation Of HPC‐Optimized Arm Processors


In this paper, the authors present performance results from Isambard, the first production supercomputer to be based on Arm CPUs that have been optimized specifically for HPC. Isambard is the first Cray XC50 “Scout” system, combining Cavium ThunderX2 Arm‐based CPUs with Cray's Aries interconnect. The full Isambard system contained over 10,000 Arm cores. In this work, we present node‐lev... » read more

Making Everything Linux-Capable


It's not clear how the edge will play out or what will be the winning formula from a hardware standpoint. But for everything beyond the end device, and possibly even including the end device, a key prerequisite will be the ability to run Linux. That means at least one processor or core within the hardware will need to run 64-bit software. In addition, systems will need to have enough storage... » read more

Week In Review: Design, Low Power


Tools & IP Arm unveiled the Cortex-R82, a 64-bit, Linux-capable Cortex-R processor targeted for next-generation enterprise and computational storage solutions. The Cortex-R82 provides 2x performance depending on workload compared to previous Cortex-R generations and provides access of up to 1TB of DRAM for advanced data processing in storage applications. It offers an optional memory manag... » read more

Week In Review: Auto, Security, Pervasive Computing


AI on edge Cadence’s Tensilica Vision P6 DSP IP will be in Kneron’s KL720, a 1.4TOPS AI system-on-chip (SoC) targeted for AI of things (AIoT), smart home, smart surveillance, security, robotics and industrial control applications. Arm announced its Arm Cortex-R82, a 64-bit, Linux-capable Cortex-R processor for enterprise and computational storage systems. The processor is designed to pr... » read more

All-in-One Vs. Point Tools For Security


Security remains an urgent concern for builders of any system that might tempt attackers, but designers find themselves faced with a bewildering array of security options. Some of those are point solutions for specific pieces of the security puzzle. Others bill themselves as all-in-one, where the whole puzzle filled in. Which approach is best depends on the resources you have available and y... » read more

Blog Review: Sept. 2


Arm's Pranay Prabhat highlights research into zero-power or low-power sensing devices and work toward designing a microcontroller that could fit with DARPA N-ZERO sensors. Mentor's Shivani Joshi provides a primer on the ODB++ standard data exchange file format that generates PCB design data files for use in fabrication, assembly, and test. Cadence's Paul McLellan shares some highlights fr... » read more
