Arm Statistical Profiling Extension: Performance Analysis Methodology


This paper presents a methodology for workload characterization and root cause analysis using the Arm Statistical Profiling Extension (SPE) demonstrated on a Neoverse N1 core. The target audience are software developers and performance analysts in software development, analysis, optimization, and tuning. This paper may also help silicon engineers to conduct performance analysis and debugging. T... » read more

Security Becoming Core Part Of Chip Design — Finally


Security is shifting both left and right in the design flow as chipmakers wrestle with how to build devices that are both secure by design and resilient enough to remain secure throughout their lifetimes. As increasingly complex devices are connected to the internet and to each other, IP vendors, chipmakers, and systems companies are racing to address existing and potential threats across a ... » read more

Software Stack For Edge AI Performance


Developing an agile software stack is important for successful AI deployment on the edge. We regularly encounter new machine learning models created from multiple AI frameworks that leverage the latest primitives and state-of-the-art ML model topologies. This Cambrian explosion has resulted from a fertile open-source community that has embraced AI and is now fueling a wide proliferation of ML m... » read more

Why Chiplets Don’t Work For All Designs


Experts at the Table: Semiconductor Engineering sat down to discuss use cases and challenges for commercial chiplets with Saif Alam, vice president of engineering at Movellus; Tony Mastroianni, advanced packaging solutions director at Siemens Digital Industries Software; Mark Kuemerle, vice president of technology at Marvell; and Craig Bishop, CTO at Deca Technologies. What follows are excerpts... » read more

RISC-V Customization Gets A Standing Ovation


Processor vendors have always tried to create a large software ecosystem around their products, because it creates stickiness and it naturally “locks-in” large numbers of customers who have invested in the creation of dedicated software. This effect is growing over time as the quantity of software is ever increasing per product: we could talk about more than 100 million lines of code in a c... » read more

Tradeoffs In DSP Design


More intelligence is now required in the front-, mid-, and back-haul for 5G/6G communication, requiring a mix of high performance, low power, and enough flexibility to accommodate constantly changing protocols and algorithms. One solution to these conflicting goals involves reconfigurable DSPs, in which the processing element is hardwired like an ASIC but still configurable for a variety of app... » read more

Improving Performance And Lowering Power In Automotive


Automotive OEMs are boosting their investments across the semiconductor ecosystem as stepping stones toward electrification and autonomy, and they are starting to encounter some of the same issues chipmakers have been wrestling with at advanced nodes — massive compute performance, thermal and power issues, reliability over extended lifetimes, and a highly diverse and geographically distribute... » read more

Not All There: Heterogeneous Multiprocessor Design Tools


The design, implementation, and programming of multicore heterogeneous systems is becoming more common, often driven by the software workloads, but the tooling to help optimize the processors, interconnect, and memory are disjointed. Over the past few years, many tools have emerged that help with the definition and implementation of a single processor, optimized for a given set of software. ... » read more

Verification And Test Of Safety And Security


Functional verification can cost as much as design, but new capabilities are piling onto an already stressed verification methodology, leaving solutions fragmented and incomplete. In a perfect world, a semiconductor device would be verified to operate according to its complete specification, and continue to operate correctly over the course of its useful life. The reality, however, is this i... » read more

The True Cost Of Software Changes


Safety and security are considered to be important in a growing number of markets and applications. Guidelines are put in place for the processes used to develop either the hardware or the software, but what they seem to ignore is that neither exists in a vacuum. They form a system when put together. Back when I was developing tools for hardware-software co-verification, there were fairly co... » read more
