Adaptive Clocking: Minding Your P-States And C-States


Larger processor arrays are here to stay for AI and cloud applications. For example, Ampere offers a 128-core behemoth for hyperscalers (mainly Oracle), while Esperanto integrates almost 10x more cores for AI workloads. However, power management becomes increasingly important with these arrays, and system designers need to balance dynamic power with system latency. As we march year over year, t... » read more

DarkGates: A Hybrid Power-Gating Architecture to Mitigate the Performance Impact of Dark-Silicon in High Performance Processors


New research paper from ETH Zurich and others. Abstract "To reduce the leakage power of inactive (dark) silicon components, modern processor systems shut-off these components' power supply using low-leakage transistors, called power-gates. Unfortunately, power-gates increase the system's power-delivery impedance and voltage guardband, limiting the system's maximum attainable voltage (i.e., ... » read more

Analytical Energy Model Parametrized by Workload, Clock Frequency and Number of Active Cores for Share-Memory High-Performance Computing Applications


New academic paper from University of Mons (Belgium) and Universidade Federal do Rio Grande do Norte (Brazil). Abstract "Energy consumption is crucial in high-performance computing (HPC), especially to enable the next exascale generation. Hence, modern systems implement various hardware and software features for power management. Nonetheless, due to numerous different implementations, we ca... » read more

Energy Harvesting and Power Management for IoT Devices in the 5G Era


Abstract: "The fifth-generation (5G) network is a fast-growing technology that impacts personal devices for both society and the economy. With the widespread Internet of Things (IoT) devices in such networks, powering and exploring energy to operate them is vital in the 5G era. Therefore, projecting and forecasting how to power IoT devices in the 5G network have already begun, with an aspira... » read more

How Semiconductor Solutions Address Safety Requirements Of Future Power Distribution Networks In Autonomous Vehicles


Open up the bonnet of any modern automobile and many of us would be hard-pressed to find anything that we could fix ourselves. With pipes and cables almost artistically integrated into the engine bay, and sleek plastic covers fitted everywhere, there is very little that can still be recognized, yet alone repaired. Perhaps the only location where we feel comfortable is the “fuse box”, or pow... » read more

Automotive AI Hardware: A New Breed


Arteris IP functional safety manager Stefano Lorenzini recently presented “Automotive Systems-on-Chip (SoCs) with AI/ML and Functional Safety” at the Linley Processor Conference. A main point of the presentation was that conventional wisdom on AI hardware markets is binary. There’s AI in the cloud: Big, power-hungry, general-purpose. And there’s AI at the edge: Small, low power, limited... » read more

Detecting Electrical Hazards Incurred By Inter-Voltage Domain Crossing In Custom SRAMs


Fast-growing markets, such as 5G, biotechnology, AI, and automotive, are driving a new wave of low-power semiconductor design requirements and, hence, more aggressive low-power management techniques are needed. Consequently, even large macros within a chip, such as SRAMs, now feature multiple voltage domains to limit power draw during light-sleep, deep-sleep, and shutdown-low-power modes. These... » read more

New Approaches For Dealing With Thermal Problems


New thermal monitoring, simulation and analysis techniques are beginning to coalesce in chips developed at leading-edge nodes and in advanced packages in order to keep those devices running at optimal temperatures. This is particularly important in applications such as AI, automotive, data centers and 5G. Heat can kill a chip, but it also can cause more subtle effects such as premature aging... » read more
