A Hierarchical Instruction Cache Tailored To Ultra-Low-Power Tightly-Coupled Processor Clusters

A technical paper titled “Scalable Hierarchical Instruction Cache for Ultra-Low-Power Processors Clusters” was published by researchers at University of Bologna, ETH Zurich, and GreenWaves Technologies. Abstract: "High Performance and Energy Efficiency are critical requirements for Internet of Things (IoT) end-nodes. Exploiting tightly-coupled clusters of programmable processors (CMPs) ha... » read more

Power Domain Implementation Challenges Escalate

The number power domains is rising as chip architects build finer-grained control into chips and systems, adding significantly to the complexity of the overall design effort. Different power domains are an essential ingredient in partitioning of different functions. This approach allows different chips in a package, and different blocks in an SoC, to continue running with just enough power t... » read more

Crisis In Data

The push toward data-driven design, debug, manufacturing and reliability holds huge promise, but the big risk is none of this will happen in an organized fashion and everyone will be frustrated. One of the clear messages coming out of DVCon this week is that standards need to be established for data. Even within large chipmakers and systems companies, the data they extract from tools is not ... » read more

The Time Dimension Of Power

Power is the flow of energy over time. While both aspects of that equation are important, they are important to different people in different ways. Energy that moves too quickly can cause significant damage. Too much energy moving over time can mean a non-competitive product, from battery-powered devices to a wide array of locations such as the datacenter. When the industry talks about power... » read more

Mixed-signal/Low-power Design

Semiconductor Engineering sat down to discuss mixed-signal/low-power IC design with Phil Matthews, director of engineering at Silicon Labs; Yanning Lu, director of analog IC design at Ambiq Micro; Krishna Balachandran, director of low power solutions marketing at [getentity id="22032" comment="Cadence"]; Geoffrey Ying, director of product marketing, AMS Group, [getentity id="22035" e_name="Syno... » read more

Automated Power Model Verification For Analog IPs

By Sierene Aymen and Hartmut Marquardt Creating macro power models for analog intellectual property (IP) blocks is essential to enable the chip assembly group to effectively integrate these blocks within their place and route environment. These macro models, which define power domains, identify IP ports as signal, power, ground, or trivial ports, and describe the associations of signal pins ... » read more

Mentor, Cadence Join Forces

Mentor Graphics and Cadence have agreed to create a single binary interface for their respective simulation and emulation platforms, allowing debug tools from one vendor to run on the other's platforms. The two have invited [getentity id="22035" e_name="Synopsys"] to join their initiative, as well. So far, there is no decision. The move proposes a single API for both [getentity id="22032"... » read more

Formal Low-Power Verification Of Power-Aware Designs

Power reduction and management methods are now all pervasive in system- on-chip (SoC) designs. They are used in SoCs targeted at power-critical applications ranging from mobile appliances with limited battery life to big-box electronics that consume large amounts of increasingly expensive power. Power reduction methods are now applied throughout the chip design flow from architectural design th... » read more

Power Management Verification Requires Holistic Approach

Semiconductor Engineering sat down to discuss power management [getkc id="10" kc_name="Verification"] issues with Arvind Shanmugavel, senior director, applications engineering at [getentity id="22021" e_name="Ansys-Apache"]; Guillaume Boillet, technical marketing manager at [getentity id="22026" e_name="Atrenta"]; Adam Sherer, verification product management director at [getentity id="22032" e_... » read more

Unraveling Power Methodologies

When working on articles, the editors at Semiconductor Engineering sometimes hear things that make them stand back and question what seems to be an industry truth. One such statement happened last month while researching a different article. The statement was: Most designs are not top-down, but in fact bottom-up when it comes to power management. The most used methodology today is that the RTL... » read more
