Simulating Multiple DSPs As Multiple x86 Processes


An increasing number of embedded designs are multi-core systems. At the pre-silicon stage, customers use a simulation platform for architectural exploration and software development. Architects want to quantify the impact of the number of cores, local memory size, system memory latency, and interconnect bandwidth. Software teams wish to have a practical development platform that is not excrucia... » read more

MCU Changes At The Edge


Microcontrollers are becoming a key platform for processing machine learning at the edge due to two significant changes. First, they now can include multiple cores, including some for high performance and others for low power, as well as other specialized processing elements such as neural network accelerators. Second, machine learning algorithms have been pruned to the point where inferencing ... » read more

RISC-V Driving New Verification Concepts


Semiconductor Engineering sat down to discuss gaps in tools and why new methodologies are needed for RISC-V processors, with Pete Hardee, group director for product management at Cadence; Mike Eftimakis, vice president for strategy and ecosystem at Codasip; Simon Davidmann, founder and CEO of Imperas Software; Sven Beyer, program manager for processor verification at Siemens EDA; Kiran Vittal, ... » read more

Heterogeneous Multi-Core HW Architectures With Fine-Grained Scheduling of Layer-Fused DNNs


A technical paper titled "Towards Heterogeneous Multi-core Accelerators Exploiting Fine-grained Scheduling of Layer-Fused Deep Neural Networks" was published by researchers at KU Leuven and TU Munich. Abstract "To keep up with the ever-growing performance demand of neural networks, specialized hardware (HW) accelerators are shifting towards multi-core and chiplet architectures. So far, thes... » read more

Shifting Auto Architectures


Domain controllers and gateways are being replaced by central processing modules and zonal gateways to handle all of the data traffic in a vehicle. Ron DiGiuseppe, automotive IP segment manager at Synopsys, talks with Semiconductor Engineering about how automotive applications are changing, what that means for engineering teams, and how they will shift as AI is increasingly deployed. » read more

Toward A Lingua Franca For Intelligent System Design


As the EDA industry is moving up further and further towards the intelligent design of full systems, this year’s Forum on Design Languages (FDL) offered a great update on the status quo with regard to where languages fit into this transition. It looks like the next step will not be one universal language as previously targeted back when there was a flurry of introductions of new programming m... » read more

Improving Simulation Throughput Using The Xcelium Parallel Logic Simulator


Simulators have been around for a long time. First, there were interpreters in the ‘80s and ‘90s, and despite being relatively slow, they were a big step up from fabricating the design and hoping it worked. However, as designs continued to increase in size, the interpreters could not keep up with simulation needs, and innovation was required for simulators to keep pace with new technology. ... » read more

SLX Multi-Objective Optimization (MOPT)


Technologies such as autonomous cars and 5G communication are seeing a rapid increase in the number of processing elements (PE) per platform. Where software professionals were used to programming one, two or a handful of cores, the game has now changed. Intel’s Many Integrated Core Architecture [3] contains up to 78 cores, Nvidia Tegra XI[2] has up to 260 cores and Adapteva’s Epiphany-V[1] ... » read more

Big Shift In Multi-Core Design


Hardware and software engineers have a long history of working independently of each other, but that insular behavior is changing in emerging areas such as AI, machine learning and automotive as the emphasis shifts to the system level. As these new markets consume more semiconductor content, they are having a big impact on the overall design process. The starting point in many of these desig... » read more

Impacts Of Reliability On Power And Performance


Making sure a complex system performs as planned, and providing proper access to memories, requires a series of delicate tradeoffs that often were ignored in the past. But with performance improvements increasingly tied to architectures and microarchitectures, rather than just scaling to the next node, approaches such as determinism and different kinds of caching increasingly are becoming criti... » read more
