Power Now First-Order Concern In More Markets
By Ann Mutschler - 10 Mar, 2022 - Comments: 0

Concerns about energy and power efficiency are becoming as important as performance in markets where traditionally there has been a significant gap, setting the stage for significant shifts in both chip architectures and in how those ICs are designed in the first place. This shift can be seen in a growing number of applications and vertical segments. It includes mobile devices, where batteri... » read more

Why Comparing Processors Is So Difficult
By Brian Bailey - 10 Mar, 2022 - Comments: 2

Every new processor claims to be the fastest, the cheapest, or the most power frugal, but how those claims are measured and the supporting information can range from very useful to irrelevant. The chip industry is struggling far more than in the past to provide informative metrics. Twenty years ago, it was relatively easy to measure processor performance. It was a combination of the rate at ... » read more

Robots Become More Useful In Factories
By John Koon - 10 Mar, 2022 - Comments: 0

Most people associate factory automation with large robotic machines, such as those that weld automobile chassis on assembly lines. But as prices drop and technology improves, robots are being deployed for smaller and more varied tasks, and they are getting better at all of them. Inside of factories, robots can significantly improve output, consistency, and reliability. They can work around ... » read more

Blog Review: March 9

Arm's Ajay Joshi investigates how to select the right benchmark for CPUs used in the Home device market, such as digital television and set-top box/over-the-top devices. Ansys' Jon Kordell checks out how reliability physics simulations and physical component characterization can support component swapping in high-reliability applications when the original part is unavailable due to supply ch... » read more

Week In Review: Manufacturing, Test
By Mark LaPedus - 04 Mar, 2022 - Comments: 0

Packaging ASE, AMD, Arm, Google, Intel, Meta, Microsoft, Qualcomm, Samsung, and TSMC have announced the formation of a consortium that will establish a die-to-die interconnect standard and foster an open chiplet ecosystem. The founding companies also ratified the UCIe specification, an open industry standard developed to establish a standard interconnect at the package level. The UCIe 1.0 s... » read more

Week In Review: Design, Low Power
By Jesse Allen - 04 Mar, 2022 - Comments: 0

Tools & IP Imperas Software introduced the RISC-V Verification Interface (RVVI). The open standard and methodology can be adapted to any configuration permitted within the RISC-V specifications. RVVI defines interfaces between RTL, reference model, and testbench for RISC-V design verification, with the aim of making RISC-V processor DV reusable. It supports multi-hart, superscalar, and out... » read more

Blog Review: March 2

Arm's Charlotte Christopherson checks out SpiNNaker1, a project to develop a massively parallel, manycore supercomputer architecture that mimicked the interactions of biological neurons, and its follow up, SpiNNaker2, a hybrid system that combines statistical AI and neuromorphic computing. Cadence's Paul McLellan looks at open and generic PDKs that can be used by researchers and in education... » read more

Week In Review: Design, Low Power
By Jesse Allen - 25 Feb, 2022 - Comments: 0

Tools & IP Codasip debuted two new customizable low power embedded RISC-V processor cores. To support embedded AI applications, the L31/L11 cores run Google’s TensorFlowLite for Microcontrollers. Codasip Studio tools can be used to customize for specific system, software, and application requirements. Licensing the CodAL description of a Codasip RISC-V core grants customers a full archit... » read more

Data Center Architectures In Flux
By Ann Mutschler - 24 Feb, 2022 - Comments: 0

Data center architectures are becoming increasingly customized and heterogeneous, shifting from processors made by a single vendor to a mix of processors and accelerators made by multiple vendors — including system companies' own design teams. Hyperscaler data centers have been migrating toward increasingly heterogeneous architectures for the past half decade or so, spurred by the rising c... » read more

Why RISC-V Is Succeeding
By Brian Bailey - 24 Feb, 2022 - Comments: 5

There is no disputing the excitement surround the introduction of the RISC-V processor architecture. Yet while many have called it a harbinger of a much broader open-source hardware movement, the reasons behind its success are not obvious, and the implications for an expansion of more open-source cores is far from certain. “The adoption of RISC-V as the preferred architecture for many sili... » read more
