Embedded Display IP Solution For 4K Resolutions


By Licinio Sousa, Synopsys, and Vassilis Androutsopoulos, Arm To meet consumers’ demands for high-resolution content and visual quality, high-end smartphones are moving from wide quad HD (WQHD) displays to ultra-high-resolution 4K displays. For AR/VR applications, since the display is closer to the eyes and must maintain visual quality, more pixels and high refresh rates are needed. Higher... » read more

Turning Down The Voltage


Designers of large, advanced-node SoCs are grappling with a number of pressures in the quest to achieve the optimal performance and power of their designs. This has turned into a challenging balancing act between using less power, especially for consumer technologies, while also providing the same or greater performance and increased functionality. [getkc id="108" kc_name="Power"] and perfor... » read more

Not All Ops Are Created Equal


Efficient and compact neural network models are essential for enabling the deployment on mobile and embedded devices. In this work, we point out that typical design metrics for gauging the efficiency of neural network architectures – total number of operations and parameters – are not sufficient. These metrics may not accurately correlate with the actual deployment metrics such as energy an... » read more

Monetizing Semiconductors From Silicon To Services


In 2016, Rambus published a think piece titled “Charting a New Course for Semiconductors.” The paper explored a diverse range of challenges faced by the industry, including increasing development costs, shrinking margins, market saturation and accelerating M&A activity. These challenges have only become more pronounced in 2018, as the newly consolidated semiconductor industry actively seeks... » read more

Artifacts Of Custom Checkers In Questa Power-Aware Dynamic Simulation


UPF provides a powerful mechanism to define a custom PA checker or assertion and provides a layer to completely separate it from design code. This is done by embedding the binding of the design and checker within the UPF file through the bind_checker command and its options. As a result, it provides a consolidated verification mechanism and allows Questa PA-SIM to access all instances of a targ... » read more

Avoiding Down Times: Monitoring, Diagnostics And Troubleshooting Of Industrial Wireless Systems


The ever-growing proliferation of wireless devices and technologies used for Internet of Things (IoT) applications, such as patient monitoring, military surveillance, and industrial automation and control, has created an increasing need for methods and tools for connectivity prediction, information flow monitoring, and failure analysis to increase the dependability of the wireless network. Inde... » read more

Signal Integrity Methodology For Double-Digit Multi-Gigabit Interfaces


As data rates for serial link interfaces such as PCI Express (PCIe) Gen 4 move into the double digits, device modeling, interconnect modeling, and analysis methodologies must continue to evolve to address the shrinking design margins and increasingly challenging compliance criteria facing today’s engineers. To mitigate risk and optimize designs, it is critical to move analysis as far upstream... » read more

2017 Coverity Scan Report


Today, open source software (OSS) development is one of the primary driving forces of technological innovation. From artificial intelligence to the Internet of Things, autonomous driving, and cloud computing infrastructure, OSS plays a pivotal role in the evolution of a wide range of technologies. But what are the implications of its dominance? To answer this, we review what we’ve learn... » read more
